• What are these errors when I try to "make" the driver of my wireless network?

  - by Tom Brito

  I got got a wireless to usb adapter, and I'm having some trouble to install the drivers on Ubuntu. First of all, the readme file say to use the "make" command, and I already got errors: $ make make[1]: Entering directory `/usr/src/linux-headers-2.6.35-22-generic' CC [M] /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c: In function ‘rtl8192_usb_probe’: /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12325: error: ‘struct net_device’ has no member named ‘open’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12326: error: ‘struct net_device’ has no member named ‘stop’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12327: error: ‘struct net_device’ has no member named ‘tx_timeout’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12328: error: ‘struct net_device’ has no member named ‘do_ioctl’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12329: error: ‘struct net_device’ has no member named ‘set_multicast_list’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12330: error: ‘struct net_device’ has no member named ‘set_mac_address’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12331: error: ‘struct net_device’ has no member named ‘get_stats’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12332: error: ‘struct net_device’ has no member named ‘hard_start_xmit’ make[2]: *** [/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o] Error 1 make[1]: *** [_module_/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-22-generic' make: *** [all] Error 2 /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/ is the path where I copied the drivers on my computer.

• Nvidia GT218 repository drivers don't work

  - by user1042840

  I upgraded all packages with sudo apt-get upgrade command on my Ubuntu 10.04 box and I have Ubuntu 12.04 3.2.0-29-generic-pae now. I have two monitors and the following GPU: 01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [NVS 300] (rev a2) After upgrading to 12.04, I somehow lost my previous setup with one common workspace stretched across two monitors. When Ubuntu starts only one monitor is on. I can see the message on the active monitor: Not optimum mode. Recommended mode: 1680x1050 60Hz I used Nvidia proprietary drivers on 10.04 but now jockey-text --list shows: xorg:nvidia_current - NVIDIA accelerated graphics driver (Proprietary, Disabled, Not in use) xorg:nvidia_current_updates - NVIDIA accelerated graphics driver (post-release updates) (Proprietary, Enabled, Not in use) When I run sudo nvidia-settings it says You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.' I typed nvidia-xconfig and rebooted, but jockey-text --list says the same after the reboot: Not in use. The same with nvidia-current - Enabled but Not in use. I also tried nvidia-173 but I ended up in tty immediately at startup so I removed it. I used to have some problems with Nvidia proprietary drivers on 10.04, I had to put paths to EDID files in /etc/X11/xorg.conf explicitly, but the resolution was as recommended and both monitors were working. If I understand correctly, nouveau drivers are used now by default because the resolution is still quite high, definitely not 800x600, xrandr showed: xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 66.0* 1280x1024 76.0 1024x768 76.0 800x600 73.0 640x480 73.0 640x400 0.0 320x400 0.0 1680x1050_60.00 (0x4f) 146.2MHz h: width 1680 start 1784 end 1960 total 2240 skew 0 clock 65.3KHz v: height 1050 start 1053 end 1059 total 1089 clock 60.0Hz However, colors seem a bit faded and blurry with nouveau drivers. Mouse cursor is invisible if it's placed inside Firefox window, and only one monitor is working. I like open source and if it's possible I'd prefer to use nouveau drivers but a few things should be fixed. I'm curious why nvidia-current drivers from the repository don't work now. I read it has something to do with the new X11 server in Ubuntu 12.04, is it true? How can I get it back to work?

• Assessing Relative Maintainability

  - by João Bragança

  We (a contractor, actually) are implementing an off the shelf system to replace a legacy homegrown system for the core domain of the company (designing widgets). Unfortunately both systems will have to run concurrently for some time, as the product just isn't ready yet. Also, the decision was made to only migrate some of the widgets from the legacy system, based on date of last sale activity. Later on a new requirement came down: certain people in the company, most of them outside of the widget development context, want to search all widgets. The search results screen has 3 pieces of data: a GUID, a human readable id that is searchable, and a brief description (may need to be searchable in the future). In the widget details, there will be multiple screens. These screens align very well along SOA / bounded context lines - a screen for marketing data, a screen for sales history, etc. UML ahead! I am probably using the wrong kind of arrows here so please forgive me. The current solution - which is not in production yet - is something like the following: Both systems will be queried and the controller will merge the results. The new system has its own proprietary query language (we've alleviated this a bit with a LINQ provider). It also puts a lot of data on the wire. 15 search results typically run about 60k of unintelligible SOAP-wrapped xml. So I would prefer to avoid querying this system directly. These two systems publish events to help us integrate with other systems, mainly an ERP system. One of these events contains all the data necessary for the search screen. I proposed the following alternative: However I am being told that 'adding another database' will create more maintenance down the road. However, I believe this to be false, as I had to add a relatively simple feature that took several hours longer than anticipated because of this merging code. I want to get a feel for which system is more maintainable in the long run. I personally have not had the burden of maintaining any large system. I want something more than my gut. Specifically I'd like to know if having more, specialized physical databases is more or less maintainable than having less larger physical databases.

• Lenovo W520 back usb port not working

  The usb port in the back of my laptop (on the right side when viewed from using perspective) is not working. Does anybody know if we can get this port working, and what the port number is. Here is my lsusb, if it can help. % lsusb Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 002: ID 8087:0024 Intel Corp.

The two usb ports on the left work just fine. EDIT: I just updated my bios from 1.32 to 1.39, no change in behaviour. The port does not even power up my devices. EDIT 2: Booted up windows, and the port is working. I went into the device manager and looked at the USB settings. I found my USB drive on Port 2, Hub 3, i just don't know how that relates to the Bus and Device numbers of linux. In windows, Smart card reader was on USB hub located at port 1 hub 2, fingerprint and bluetooth were on USB hub located at port 1 hub 1 EDIT 3: Went and looked at this SO post. Tried to look at my kern.log file with tail -f /var/log/kern.log. Got some activity when plugging/removing devices in other ports, but nothing happens when connecting a device into that port. It really looks disabled. Looked at my usb1-4 sys/bus/usb/devices/usb1/power/control and they are all set on auto. As expected, usb4 have version 3.00, the others (usb1-usb3) are 2.00.

• GitLab on a fresh Ubuntu 13 EC2 instance

  - by Polly

  I've spun up a fresh Amazon EC2 instance for a micro Ubuntu 13 server to be used as a GitLab server. I know the specs are a little low, but it should serve well for my purposes. It has an elastic (static) IP address that I have created an A record for git.mydomain.com. The first thing I did to the instance was add 1GB of swap to keep it happy from a memory perspective. I then set the hostname of the box to be git.mydomain.com and followed https://github.com/gitlabhq/gitlabhq/blob/6-2-stable/doc/install/installation.md to the letter. Everything seems to have worked, except for the web server side of things. Doing a gitlab:check shows the following: Checking Environment ...

• Toshiba wireless is blocked

  - by zorrillo

  I have the same problem, a 32 bits toshiba nb255, it first had the windows 7 bu next I installed the ubuntu 11.04. The wifi does not turn on. I used the following issues the commands rfkill unblock wlan0, sudo ifconfig wlan0 down; they were not able. by setting up the bios in advanced menu, the wireless communication sw in ON, but it did not work also. neither the utilities toshiba nor utilities of ubuntu (wicd, wifi radar). by using gedit to file group, nothing. by installing madwifi packet, nothing. by exporting the wifi driver from windows to ubuntu, by means of the NDISwrapper packet, neither.

I only see the device is up by protocols and down phisically, My question is, is it possible to enable or not shutdown physically the device?, because in the toshiba model nb255 the wifi is not set up/down bye means of a physical switch, but by means a combination of Fn + F8 (only for windows 7, no one more), Is there one possibility to configure the hot keys in ubuntu?

• What are the best practices to use NHiberante sessions in asp.net (mvc/web api) ?

  - by mrt181

  I have the following setup in my project: public class WebApiApplication : System.Web.HttpApplication { public static ISessionFactory SessionFactory { get; private set; } public WebApiApplication() { this.BeginRequest += delegate { var session = SessionFactory.OpenSession(); CurrentSessionContext.Bind(session); }; this.EndRequest += delegate { var session = SessionFactory.GetCurrentSession(); if (session == null) { return; } session = CurrentSessionContext.Unbind(SessionFactory); session.Dispose(); }; } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); var assembly = Assembly.GetCallingAssembly(); SessionFactory = new NHibernateHelper(assembly, Server.MapPath("/")).SessionFactory; } } public class PositionsController : ApiController { private readonly ISession session; public PositionsController() { this.session = WebApiApplication.SessionFactory.GetCurrentSession(); } public IEnumerable<Position> Get() { var result = this.session.Query<Position>().Cacheable().ToList(); if (!result.Any()) { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound)); } return result; } public HttpResponseMessage Post(PositionDataTransfer dto) { //TODO: Map dto to model IEnumerable<Position> positions = null; using (var transaction = this.session.BeginTransaction()) { this.session.SaveOrUpdate(positions); try { transaction.Commit(); } catch (StaleObjectStateException) { if (transaction != null && transaction.IsActive) { transaction.Rollback(); } } } var response = this.Request.CreateResponse(HttpStatusCode.Created, dto); response.Headers.Location = new Uri(this.Request.RequestUri.AbsoluteUri + "/" + dto.Name); return response; } public void Put(int id, string value) { //TODO: Implement PUT throw new NotImplementedException(); } public void Delete(int id) { //TODO: Implement DELETE throw new NotImplementedException(); } } I am not sure if this is the recommended way to insert the session into the controller. I was thinking about using DI but i am not sure how to inject the session that is opened and binded in the BeginRequest delegate into the Controllers constructor to get this public PositionsController(ISession session) { this.session = session; } Question: What is the recommended way to use NHiberante sessions in asp.net mvc/web api ?

• Is Ubuntu recognizing and/or using my NVIDIA graphics card?

  - by user212860

  This is my first post here, and I'm pretty new to Ubuntu/Linux. I currently have no other OS except for Ubuntu 13.10. (I used to have Win7 until i got a new terabyte hard drive). My current PC build, if any of this helps: CPU: Intel i5 quad-core Graphics: NVIDIA GeForce GTX 650 RAM: 8 GB HDD: 1 TB SATA 3 Motherboard: MSi Z77 A-G41 OS Ubuntu 13.10 So I recently installed Ubuntu 13.10 and put Steam on it, and I'm seeing that my games run a lot slower than they did when I had Win7. I figured it was a graphics problem, so I checked System Settings Details Overview. It says in "Graphics" that I have "Gallium 0.4 on NVE7" (don't really know what that is). Does this mean that Ubuntu is not using my graphics card? In System Settings Software & Updates Additional Drivers, it clearly shows like this: NVIDIA Corporation: GK107 [GeForce GTX 650] -This device is using an alternative driver (And then it shows a list of drivers that I can switch back and forth to) So this is a bit confusing. In Software and Updates, it clearly shows that I have my NVIDIA card installed, and that I have a driver selected for it. But in System Settings, it shows I have some Gallium 0.4 thing. I had done a bit of research, and ended up typing command: "lspci|grep VGA" in the Terminal. It showed this in response: VGA compatible controller: NVIDIA Corporation GK107 [GeForce GTX 650] (rev a1) The Terminal seems to recognize my graphics card. What it looks like to me, is that I don't have the proper driver, and I might be using my CPU's integrated graphics. When I switch around which driver I am using in that list, it still does not see my card in System Settings. Some of the drivers in the list give me some sort of OpenGL error when I try to run a game. It might just be that my games are running slow because the game developers have not optimized it for Ubuntu that well. However, that still doesn't take away from the fact that System Settings is not showing my NVIDIA card. TL;DR Version: How do I know if my video card is being recognized/used? If my video card is not being used, what is the best way fix that? Please make your answers easy to understand. I do not mind wordy responses, as long as I can follow what you're saying. Any help would be greatly appreciated! Thanks, Jabber5

• Reasons NOT to use JSF [closed]

  - by Vain Fellowman

  I am new to StackExchange, but I figured you would be able to help me. We're crating a new Java Enterprise application, replacing an legacy JSP solution. Due to many many changes, the UI and parts of the business logic will completely be rethought and reimplemented. Our first thought was JSF, as it is the standard in Java EE. At first I had a good impression. But now I am trying to implement a functional prototype, and have some really serious concerns about using it. First of all, it creates the worst, most cluttered invalid pseudo-HTML/CSS/JS mix I've ever seen. It violates every single rule I learned in web-development. Furthermore it throws together, what never should be so tightly coupled: Layout, Design, Logic and Communication with the server. I don't see how I would be able to extend this output comfortably, whether styling with CSS, adding UI candy (like configurable hot-keys, drag-and-drop widgets) or whatever. Secondly, it is way too complicated. Its complexity is outstanding. If you ask me, it's a poor abstraction of basic web technologies, crippled and useless in the end. What benefits do I have? None, if you think about. Hundreds of components? I see ten-thousands of HTML/CSS snippets, ten-thousands of JavaScript snippets and thousands of jQuery plug-ins in addition. It solves really many problems - we wouldn't have if we wouldn't use JSF. Or the front-controller pattern at all. And Lastly, I think we will have to start over in, say 2 years. I don't see how I can implement all of our first GUI mock-up (Besides; we have no JSF Expert in our team). Maybe we could hack it together somehow. And then there will be more. I'm sure we could hack our hack. But at some point, we'll be stuck. Due to everything above the service tier is in control of JSF. And we will have to start over. My suggestion would be to implement a REST api, using JAX-RS. Then create a HTML5/Javascript client with client side MVC. (or some flavor of MVC..) By the way; we will need the REST api anyway, as we are developing a partial Android front-end, too. I doubt, that JSF is the best solution nowadays. As the Internet is evolving, I really don't see why we should use this 'rake'. Now, what are pros/cons? How can I emphasize my point to not use JSF? What are strong points to use JSF over my suggestion?

• MVC Can the model know ANYTHING about the view?

  - by AwDogsGo2Heaven

  I'm working on a game, and without getting into any details I am using MVC "patterns", "rules" or whatever you want to call it to make the game. The view includes everything needed to draw things on the screen, the controller passes input to the model. And the Model contains game logic. Here's my problem, the game is being made for mobile devices that vary in screen sizes. I feel my model needs to know the view size so it can appropriately adjust for it. I've thought about it for a while I could put all the adjustments in the view, but it just seems inefficient to translate the model positioning to the view's needed positioning every time. If the model knows the size it only needed to adjust itself once. So my question is can I pass the view size to the model without 'breaking' MVC? I feel personally they are still decoupled this way because a size is just a number, I could still change the view any time as long as it has a size. But I wanted to get a community response on this because I haven't seen many discussions of MVC being used in a game. (And to be clear I don't want an answer of why I shouldn't use it in a game, but do I break MVC by letting it know the view's size) EDIT - More details on the game's needs and why I wanted to pass the view. Some objects positions need to be set relative to the edge of the screen (such as UI elements) so that they appear relatively in the same place. Sprite sizes are not stretched if the window size is wider such as an IPhone 5 screen. They will just be placed relatively to the screen edge. .If I gave it to the view to handle this, I will need a flag saying that this element is positioned say x number of pixels from TOP BOTTOM RIGHT LEFT. Then allow the view to draw it with that information. Its acceptable, I just wanted to know if there was a better way while still being MVC because it seems this way will be repeating a logic over and over, where as if I knew the view size in the model, I could convert all the relative positions into absolute positions in one run, but with this I have to convert on every update to the screen.

• Languages and VMs: Features that are hard to optimize and why

  - by mrjoltcola

  I'm doing a survey of features in preparation for a research project. Name a mainstream language or language feature that is hard to optimize, and why the feature is or isn't worth the price paid, or instead, just debunk my theories below with anecdotal evidence. Before anyone flags this as subjective, I am asking for specific examples of languages or features, and ideas for optimization of these features, or important features that I haven't considered. Also, any references to implementations that prove my theories right or wrong. Top on my list of hard to optimize features and my theories (some of my theories are untested and are based on thought experiments): 1) Runtime method overloading (aka multi-method dispatch or signature based dispatch). Is it hard to optimize when combined with features that allow runtime recompilation or method addition. Or is it just hard, anyway? Call site caching is a common optimization for many runtime systems, but multi-methods add additional complexity as well as making it less practical to inline methods. 2) Type morphing / variants (aka value based typing as opposed to variable based) Traditional optimizations simply cannot be applied when you don't know if the type of someting can change in a basic block. Combined with multi-methods, inlining must be done carefully if at all, and probably only for a given threshold of size of the callee. ie. it is easy to consider inlining simple property fetches (getters / setters) but inlining complex methods may result in code bloat. The other issue is I cannot just assign a variant to a register and JIT it to the native instructions because I have to carry around the type info, or every variable needs 2 registers instead of 1. On IA-32 this is inconvenient, even if improved with x64's extra registers. This is probably my favorite feature of dynamic languages, as it simplifies so many things from the programmer's perspective. 3) First class continuations - There are multiple ways to implement them, and I have done so in both of the most common approaches, one being stack copying and the other as implementing the runtime to use continuation passing style, cactus stacks, copy-on-write stack frames, and garbage collection. First class continuations have resource management issues, ie. we must save everything, in case the continuation is resumed, and I'm not aware if any languages support leaving a continuation with "intent" (ie. "I am not coming back here, so you may discard this copy of the world"). Having programmed in the threading model and the contination model, I know both can accomplish the same thing, but continuations' elegance imposes considerable complexity on the runtime and also may affect cache efficienty (locality of stack changes more with use of continuations and co-routines). The other issue is they just don't map to hardware. Optimizing continuations is optimizing for the less-common case, and as we know, the common case should be fast, and the less-common cases should be correct. 4) Pointer arithmetic and ability to mask pointers (storing in integers, etc.) Had to throw this in, but I could actually live without this quite easily. My feelings are that many of the high-level features, particularly in dynamic languages just don't map to hardware. Microprocessor implementations have billions of dollars of research behind the optimizations on the chip, yet the choice of language feature(s) may marginalize many of these features (features like caching, aliasing top of stack to register, instruction parallelism, return address buffers, loop buffers and branch prediction). Macro-applications of micro-features don't necessarily pan out like some developers like to think, and implementing many languages in a VM ends up mapping native ops into function calls (ie. the more dynamic a language is the more we must lookup/cache at runtime, nothing can be assumed, so our instruction mix is made up of a higher percentage of non-local branching than traditional, statically compiled code) and the only thing we can really JIT well is expression evaluation of non-dynamic types and operations on constant or immediate types. It is my gut feeling that bytecode virtual machines and JIT cores are perhaps not always justified for certain languages because of this. I welcome your answers.

• Why one loop is performing better than other memory wise as well as performance wise?

  - by Mohit

  I have following two loops in C#, and I am running these loops for a collection with 10,000 records being downloaded with paging using "yield return" First foreach(var k in collection) { repo.Save(k); } Second var collectionEnum = collection.GetEnumerator(); while (collectionEnum.MoveNext()) { var k = collectionEnum.Current; repo.Save(k); k = null; } Seems like that the second loop consumes less memory and it faster than the first loop. Memory I understand may be because of k being set to null(Even though I am not sure). But how come it is faster than for each. Following is the actual code [Test] public void BechmarkForEach_Test() { bool isFirstTimeSync = true; Func<Contact, bool> afterProcessing = contactItem => { return true; }; var contactService = CreateSerivce("/administrator/components/com_civicrm"); var contactRepo = new ContactRepository(new Mock<ILogger>().Object); contactRepo.Drop(); contactRepo = new ContactRepository(new Mock<ILogger>().Object); Profile("For Each Profiling",1,()=>{ var localenumertaor=contactService.Download(); foreach (var item in localenumertaor) { if (isFirstTimeSync) item.StateFlag = 1; item.ClientTimeStamp = DateTime.UtcNow; if (item.StateFlag == 1) contactRepo.Insert(item); else contactRepo.Update(item); afterProcessing(item); } contactRepo.DeleteAll(); }); } [Test] public void BechmarkWhile_Test() { bool isFirstTimeSync = true; Func<Contact, bool> afterProcessing = contactItem => { return true; }; var contactService = CreateSerivce("/administrator/components/com_civicrm"); var contactRepo = new ContactRepository(new Mock<ILogger>().Object); contactRepo.Drop(); contactRepo = new ContactRepository(new Mock<ILogger>().Object); var itemsCollection = contactService.Download().GetEnumerator(); Profile("While Profiling", 1, () => { while (itemsCollection.MoveNext()) { var item = itemsCollection.Current; //if First time sync then ignore and overwrite the stateflag if (isFirstTimeSync) item.StateFlag = 1; item.ClientTimeStamp = DateTime.UtcNow; if (item.StateFlag == 1) contactRepo.Insert(item); else contactRepo.Update(item); afterProcessing(item); item = null; } contactRepo.DeleteAll(); }); } static void Profile(string description, int iterations, Action func) { // clean up GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); // warm up func(); var watch = Stopwatch.StartNew(); for (int i = 0; i < iterations; i++) { func(); } watch.Stop(); Console.Write(description); Console.WriteLine(" Time Elapsed {0} ms", watch.ElapsedMilliseconds); } I m using the micro bench marking, from a stackoverflow question itself benchmarking-small-code The time taken is For Each Profiling Time Elapsed 5249 ms While Profiling Time Elapsed 116 ms

• Windows Azure Directory Sync Generic Failure

  - by Armand

  Ok so I have a domain that I want to sync to Office365 but when I start the Windows Azure Active Directory Sync tool Configuration Wizard I get an error with the following details: System.Management.ManagementException: Generic failure at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext() at Microsoft.Online.DirSync.Common.MiisAction.GetTargetMA() at Microsoft.Online.DirSync.Common.MiisAction.IsSyncInProgress() at Microsoft.Online.DirSync.Common.PrerequisiteChecks.ThrowIfSyncInProgress() at Microsoft.Online.DirSync.UI.IntroductionWizardPage.PrerequisiteValidation() at Microsoft.Online.DirSync.UI.IntroductionWizardPage.OnLoad(EventArgs e) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) I have searched far and wide to no avail, this happens before I can even enter any details. A few notes: The server is not the domain controller Sharepoint 2013 is installed on this server The account I log in with and run the application with is a domain and enterprise admin I right click and run as administrator when I start the application So when I click continue on the error and go through the steps I get two possible scenarios that change from time to time at now predictable rate: 1) I just get an error, generic failure. 2) I get an error "Cannot start service MSOnlineSyncScheduler on computer '.'." Any help?

• Windows CE 6.0 time setting in registry being overrided

  - by JaminSince83

  I have asked this question on stack overflow but its probably better suited here. So I have a Motorola MC3190 Mobile Barcode scanning device with Windows CE 6.0. Now I want to get the device to sync its date/time on boot up with our domain controller using a registry file that I have created. I have used this registry file below to get close to what I require. REG 1 REGEDIT4 [HKEY_LOCAL_MACHINE\Services\TIMESVC] "UserProcGroup"=dword:00000002 "Flags"=dword:00000010 "multicastperiod"=dword:36EE80 "threshold"=dword:5265C00 "recoveryrefresh"=dword:36EE80 "refresh"=dword:5265C00 "Context"=dword:0 "Autoupdate" = dword:1 "server" = "NAMEOFMYSERVER" "ServerRole" = dword:0 "Trustlocalclock" = dword:0 "Dll"="timesvc.dll" "Keep"=dword:1 "Prefix"="NTP" "Index"=dword:0 [HKEY_LOCAL_MACHINE\nls] "DefaultLCID" = dword:00000809 [HKEY_LOCAL_MACHINE\nls\overrides] "LCID" = dword:00000809 [HKEY_LOCAL_MACHINE\Time] @ = "UTC" "TimeZoneInformation"=hex:\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 [HKEY_LOCAL_MACHINE\Time Zones] @ = "UTC" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Clock] "AutoDST" = dword:00000000 Now it gets the correct date and shows the time zone correctly however the time is always 5 hours behind on Eastern Standard Time, which is really annoying. I have researched heavily into this and this question has been asked before here As you will see I have copied what it suggests but it doesnt work. Something is overiding the time which I dont understand enough about to resolve. I cannot find any other setting to get it to set the time correctly. Any help would be greatly appreciated.

• MS NPS denying access, can't validate server certificate

  - by Fred Weston

  At my office we use a Cisco WLC2504 wireless controller and starting about a week ago we started having problems with users connecting to one of our secure wireless network. We are running AD on Windows Server 2008 R2 and use network policy server to control access to our wireless network. When I look at the logs in event viewer after a failed connection attempt I see an access reject message: Reason Code: 262 Reason: The supplied message is incomplete. The signature was not verified. Looking this up on Google I found this article: http://support.microsoft.com/kb/838502 I tried disabling server certificate validation on my computer and as soon as I did that I was able to connect to the network, so it seems that there is some sort of certificate validation issue. I'm not sure which certificate is unable to be validated or how to fix it. This used to work and stopped suddenly by itself so I am thinking a certificate may have expired. When I go to NPS Policies Network Policies My policy Constraints Auth methods Microsoft PEAP and view the properties, the certificae specified here expires in 2016, so doesn't seem as though this could be the problem. Any suggestions on how to troubleshoot this issue?

• HP P212 hangs on Initializing

  - by user927586

  I'm in trouble... Server: HP Microserver N36L Storage: HP P212/256 with BBWC Drives: 4 WD 2 Tb While expanding the RAID 5 array from 3 to 4 drives, the server rebooted itself. Expansion was at 76%. Now at boot the P212 seems to hang on initializing. After some time screen resets and the server boots, but in the os (Windows Server 2008R2) the P212 has errors (error code 10) and it's not seen by the HP ACU. Whats' going on? It's trying to complete the expansion? It's trying to make all over the expansion? It's simply stuck? What should I do? I NEED the data on the array! PS In the server BIOS, on the hd boot priority, the server still reports the array logical drive... maybe it's a good sign... PPS I'm not at the server physical location, so I cannot tell if the drives in the array are being accessed (that would be the case if the controller it's redoing/completing the expansion process) or not right now. Bye Dario

• Outlook 2007 unable to connect to exchange server

  - by mattwarren

  I came into the office a week ago and outlook has refused to connect ever since, it just says "Disconnected" in the bottom right-hand corner. I've tried restarting it, rebooting Windows etc. I'm the only one if our office who is having this problem, so it's not a general problem with the server. Things I've tried Pinging the server via IP address and host name, both work fine Connecting via OWA, this works using the same machine name Connecting to Exchange via HTTP ("Outlook Anywhere") doesn't work None of the suggestions in this question helped, http://serverfault.com/questions/21755/can-ping-exchange-server-cant-connect-outlook-to-it Disabling Windows firewall on my laptop also has no effect. There are no items in the event viewer that indicate that anything it up. Also no permissions have changed on the server since when it worked. Update: I've just tried logging onto a completely different PC, using my domain controller user-name/password. When I setup outlook on there it also fails, so the problem isn't specific to 1 pc/outlook it's something about my particular user name, but not when using OWA? What else can I do to diagnose this, any suggestions?

• Windows 7 intermittently drops wired internet/lan connection.

  - by CraigTP

  In a nutshell, my Windows 7 Ultimate PC intermittently drops it's internet connection. Why? Background: My PC is wired to my ADSL modem/router which is directly connected to the phone line. I also have wireless connectivity turned on within the router for a laptop to connect wirelessly. Every few hours or so, when using my PC, I find I cannot access the internet and pages will not load. Eventually, Windows7 will update the network icon in the task-tray to show the exclamation mark symbol on the network icon. Opening up the Network And Sharing Centre will show the red cross between the "Multiple Networks" and "The Internet". Here's a picture of the "Network And Sharing Centre" (grabbed when everything was working!) As you can see, I'm running Sun's VirtualBox on this machine and that creates a Network connection for itself. This doesn't seem to affect the intermittent dropping (i.e. the intermittent drops occur whether the VirtualBox connection is in use or not). When the connection does drop, I cannot access any internet pages, nor can I access the router's web admin page at http://192.168.1.1/, so I'm assuming I've lost all local LAN access too. It's definitely not the router (or the internet connection itself) as my laptop, using the wireless connection (and running Vista Home Premium) continues to be able to access the internet (and the router's web admin pages) just fine. Every time this happens, I can immediately restore all internet and LAN access by opening Network Adapter page, disabling the "Local Area Connection" and then re-enabling it. Give it a few seconds and everything is fine again. I assume this is because, beneath the GUI, it's effectively doing an "ipconfig /release" then "ipconfig /renew". Why does this happen in the first place, though? I've googled for this and seen quite a few other people (even on MSDN/Technet forums) experiencing the same or almost the same problem, but with no clear resolution. Suggestions of turning off IPv6 on the LAN adapter, and ensuring there's no power management "sleeping" the network adapter have been tried but do not cure the problem. There does not seem to be any particular sequence of events that cause it to happen either. I've had it go twice in 20 minutes when just randomly browsing the web with no other traffic, and I've also had it go once then not go again for 2-3 hours with the same sort of usage. Can anyone tell me why this is happening and how to make it stop? EDIT: Additional information based upon the answer provided so far: Firstly, I forgot the mention that this is Windows 7 64 bit if that makes any difference at all. I mentioned that I don't think the VirtualBox network adpater is causing this problem in any way, and I also have VirtualBox installed on two other machines, one running Vista Home Premium and the other running XP. Neither of these machine experience the same network connectivity issues as the Windows 7 machine. The IP assignment for the Windows 7 machine is the same both before and after the "drop". I have a DHCP server on the router issuing IP Addresses, however my Windows 7 machine uses a static address. Here's the output from "ipconfig": Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.2(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 192.168.1.1 NetBIOS over Tcpip. . . . . . . . : Enabled Within the system's event logs, the only event that relates to the connection dropping is a "DNS Client Event" and this is generated after the connection has dropped and is an event detailing that DNS information can't be found for whatever website I may be trying to access, just as the connection drops: Log Name: System Source: Microsoft-Windows-DNS-Client Event ID: 1014 Task Category: None Level: Warning Keywords: User: NETWORK SERVICE Description: Name resolution for the name weather.service.msn.com timed out after none of the configured DNS servers responded. The network adapter chipset is Realtek PCIe GBE Family Controller and I have confirmed that this is the correct chipset for the motherboard (Asus M4A77TD PRO), and in fact, Windows Update installed an updated driver for this on 12/Jan/2009. The details of the update say that it's a Realtek software update from December 2009. Incidentally, I was still having the same intermittent problems prior to this update. It seems to have made no difference at all. EDIT 2 (1 Feb 2010): In my quest to solve this problem, I have discovered some more interesting information. On another forum, someone suggested that I should try running Windows in "Safe Mode With Networking" and see if the problem continues to occur. This was a fantastic suggestion and I don't know why I didn't think of it sooner myself. So, I proceeded to run in Safe Mode with Networking for a number of hours, and amazingly, the "drops" didn't occur once. It was a positive discovery, however, due to the intermittent nature of the original problem, I wasn't completely convinced that the problem was cured. One thing I did note is that the fan on my GFX card was running alot louder than normal. This is due to the fact that I have an ASUS ENGTS250 graphics card (http://www.asus.com/product.aspx?P_ID=B6imcoax3MRY42f3) which had a known problem with a noisy fan until a BIOS update fixed the issue. (See the "Manufacturer Response" here: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121334 for details). Well, running in safe mode had the fan running (incorrectly) at full speed (as it did before the BIOS update), but with an (apparently) stable network connection. Obviously some driver was not loaded for the GFX card when in Safe Mode so this got me thinking about the GFX card (since the very noisy fan was quite obvious when running in Safe Mode). I rebooted into normal mode, and found that Nvidia had a very up-to-date new driver for my GFX card (only about 1 week old), so I downloaded the appropriate driver and installed it. After installation and a reboot, I was able to use my PC for an entire day with NO NETWORK DROPS!!! This was on Saturday. However, on the Sunday, I also had my PC for pretty much the entire day and experienced 2 network drops. No other changes have been made to my PC in this time. So, the story seems to be that updating my graphics card drivers seems to have improved (if not completely fixed) the issue, however, I'm still searching for a proper fix for this problem. Hopefully, this information may help anyone who may have additional ideas as to why this problem is occuring in the first place. (And why does new GFX card drivers have anything to do with the network?) I appreciate everyone's feedback so far. However, I'll have to ask once more if anyone has any further ideas of how to fix this particular problem? Thanks in advance.

• The Message Queuing service failed to join the computer's domain 'DOMAIN' Error 0xc00e0025

  - by SimonGoldstone

  Struggling to get MSMQ installed in Domain Integration mode on Windows 2012 (Azure). So far, I've provisioned a brand new Windows Server 2012 (R2) machine on the Azure platform and installed the Active Directory role and promoted the machine to a domain controller. Once the AD was in place, I then added the MSMQ feature, along with the Directory Integration add on. However, it will not install in AD integration mode. It will only work in Workgroup mode. I can verify this by running the following powershell command: New-MSMQQueue -name Queue1 -queuetype Public When I run this command, I get the following error: New-MsmqQueue : A workgroup installation computer does not support the operation. The event viewer reveals to errors in the Application log: 1. The Message Queuing service failed to join the computer's domain 'DOMAIN'. Error 0xc00e0025: 2. Message Queuing was unable to create the msmq (MSMQ Configuration) object in Active Directory Domain Services. Error c00e0025h: I'm struggling here. Any advice?

• UNC Path fails by IP "no network provider accepted the given network path", but works using hostname

  - by BoyMars

  I have an unusual problem with a Windows Server 2003 (Standard x86) box. It appears the machine will not accept connections to its shares (locally and from other domain member servers) by using its ip address in a UNC path. The error returned is: "no network provider accepted the given network path" This is the case with the machine's ip address: \\10.0.8.x and even the loopback address: \\127.0.0.1 \\localhost does not work... but using the hostname (fqdn or not) works: \\server & \\server.domain.local The local windows firewall for this server is off, ping/rdp/other services respond fine using the IP address. The following services are running and have been restarted: Computer Browser Workstation Server The server itself has been rebooted too. Event 8032 in the system log indicates that: The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{29A6A925-AFB3-47E2-BA59-DDA086DEAE7A}. The backup browser is stopping. The domain controller has not been restarted, no other servers have experienced this problem, yet there are a number of browser (8021) related errors in the logs on this server. Does anyone have any suggestions? I would like to avoid rejoining this server to the domain if possible.
