• Getting Started with windows server 2008/2012

  - by hbrock

  First let me say, I am a programmer(not a super star) but I want to get more into the system/network administration side of things. This because there are more jobs for system/network administrators in the area I live. Right now I am using virtual machines to learn how windows 2008/2012 works and to build labs with. But how would I prove to an employer what my skill set is with windows 2008/2012? As a programmer I would point to my past projects, code samples, and so on. Thanks for any help.

• How to make sure you server NIC performance is at best on Windows?

  - by Bobb

  I realised that I followed some obscure paper on setting NICs on Windows for too long. It might be outdated with new hardware released in past couple of years and with W2008R2. I read a bit about offloading and RSS settings on Windows and I realiased that it is very much circumstantial. Noone can really say - enable that and disable this. etc. So what I really want is for my next server try and setup testing environment and measure how my particular application will behave with different settings. The target is going to be latency of TCP primarily. Please note I am talking about latency inside the box. Are there precision tools for Windows to measure latency (down to microseconds)? P.S. I know this is not easy question. Windows time drift is awful problem for any precision test but still I am sure I am not the fist person to need that... Please share your experience

• Can a RAID 4 disk setup crash if only 1 hard disk fails?

  - by Steve Rodrigue

  I am a web developer. I have not much experience in hardware. For this reason, I use managed servers. This morning, one of the drives in our setup failed. However, the full site went down. I asked my web host what happened and he replied that the hard disk failed in such a way that the RAID controller couldn't work properly. The array was set up as RAID 4. Do you guys ever seen that before? Is it possible? Thanks for any help on this guys. I need to know if my web host is honest with me.

• View Security Server and Direct Connection

  - by Poort443

  I have a Security Server for my connections from the Internet. This works fine, accept when I enable "Direct Connection to the desktop". I found the following statement on this: If you bypass the secure connection, the client must establish a direct RDP communication to the desktop virtual machine over RDP (port 3389). Does this mean I have to open 3389 (RDP) to the Internet if I want to use Direct Connections? If I disable Direct Connections to get my Security Server working, I have to disable it on my Connection Server. It's my understanding that this means that if I reboot my Connection Server, all the View clients get disconnected. Is there a way I can disable "Direct Connections" for the Security Server, while enabling it for access from the LAN? Tia.

• Exchange Failover Solution

  - by Dan

  I've been given the task to come up with an exchange solution that will support 200 users total throughout 4 states. 1GB per user. It needs to have a failover solution,The failover must reside in another location. There is an mpls that connects the locations. I am hoping to get recomendations on hardware, software setups. I recently worked with some big name reps and they steered me in the wrong direction and now I'm a few days away from my proposal date with bogus quotes and scrambling for a solution. I used to manage a standalone 2003 exchange server for years and am at a loss now with figuring out a clustering/failover...Any help would be greatly appreciated. thank you

• How to put fear of God (law) into Wi-Fi hacking neighbors [closed]

  - by Shakehar

  I live in an apartment and some new guys have apparently moved into one of the apartments. They have been shamelessly hacking into my WiFi. Mine was initially a WEP encrypted network and out of laziness I just limited and reserved the IPS on my router for the people in my house. Yesterday I had to free up an IP for a guest in my house but before he could join the network these guys connected in. I have changed my encryption to WPA2 and hope they dont have the hardware/patience required to hack into it, but there are many wi-fi networks in my apartment most of which are secured using WEP. I don't really want to call the police on them. Is there any way to deter them from misusing other people's wi-fi ? I have gone through I think someone else has access to my wireless network. What next? but I have already taken the steps mentioned there.

• System stuttering caused by hard drive

  - by LukLed

  My system keeps freezing for about 1-2 second every time I try to do something. For example, when I enter URL in browser, it freezes and starts working after few seconds. It is probably related to hard drive. I installed HD tune and when benchmark is in progress, causing constant disk use, everything works fine in background, there are no lags. What can be the reason of this issue? My hardware is Acer Aspire 7740G-6969 running on Windows 7.

• Default maximum heap size -- Ubuntu 10.04 LTS, openjdk6-jre

  - by sachin

  I just installed openjdk6-jre on Ubuntu 10.04 java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu1~10.04.1) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode) Every time I run "java" I get this error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. This can be solved by specifying a maximum heap size and running "java -Xmx256m" But is there anyway to permanently fix this error (i.e. set the default heap size to 256MB so that I do not need to specify the max heap size every time I run the command)

• Windows XP 32-bit + RocketRaid 622 + 4 x 3TB = not quite a RAID setup

  - by gmoney

  I'm looking to make a 6TB RAID 10 array from my new pile of drives under Windows XP 32-bit, however they are only for auxiliary storage. After adding all the drives to an array, and initializing them XP sees only a fraction of the storage, 2TB. I'm assuming this has to do with MBR vs GPT. Is making a series of 2TB volumes and then spanning my only solution? Most questions online have to do with booting from this setup, but I'm just using them as extra storage. Hardware: 4 x 3TB Hitachi Deskstars + RocketRaid 622 + Sans Digital TR8M TowerRAID. The array is connected via eSATA.

• Running 32 bit SQL Server 2005 on 64 bit Windows Server?

  - by TooFat

  If I have a 32 bit version of SQL Server 2005 running on a 64 bit Windows Server does the max amount of memory avail. the SQL Server process increase from 2gb to 4gb. In reading this blog entry by Mark Russinovich in which he states that "All Microsoft server products and data intensive executables in Windows are marked with the large address space awareness flag" and "Because the address space on 64-bit Windows is much larger than 4GB, something I’ll describe shortly, Windows can give 32-bit processes the maximum 4GB that they can address and use the rest for the operating system’s virtual memory." which leads me to believe that the answer is "yes" but I not totally confident.

• 'hijacking' gui and mapping certain controls to certain functions. VNC. TouchOSC

  - by Nick

  I need a VNC LIKE application which rather than sharing the screen, can take control of a specific application and then share that functionality across a network to multiple clients. Obviously, VNC requires use of the mouse and therefore only one user can do something at one time, this is NOT what I am after. I am after something that can hijack the graphic user interface, map certain controls, and then display them in another piece of software (perhaps like TOUCHOSC) The software I would like to map and share is called YAMAHA STUDIO MANAGER and is used to control certain Yamaha audio hardware, and in my case a Yamaha LS9 and M7CL mixing console. Its free.

• IIRF - Redirecting all traffic to the http equivalent

  - by GordonB

  I'm using IIRF and having some trouble getting it to redirect all traffic to the secure version of my sites. So... I have a website with about 20 apps in virtual directories in IIS6. The website takes 80 and 443 traffic. I want to use IIRF to redirect all port 80 traffic EG; http://myserver/app1/page1/param1 http://myserver/app2/ http://myserver To the secure equivalent (https). Here's my config so far; # Iirf.ini # # ini file for IIRF # RewriteLogLevel 1 RewriteLog D:\Websites\Apptemetry\IirfLogs RewriteEngine ON StatusInquiry ON IterationLimit 5 RewriteLogLevel 3 RewriteCond %{HTTPS} off RewriteCond %{SERVER_PORT} ^80$ RedirectRule ^http(.*)$ https$1 Can anyone advise the correct configuration to use, to redirect all traffic?

• parallel to usb driver windows 7 dot matrix printer

  - by user975234

  I recently built a new Core i5 system with Windows 7 Professional. I had planned to hook up my TVS MSP 250 XL printer using a USB to parallel cable Once I plug the cable in, Windows 7 recognizes it as an IEEE-1284 controller and automatically installs the appropriate driver. However, in the status window it reports the following: "USB Printing Support -- Ready to use" "No Printer Attached -- Ready to use" When I then go ahead and manually add the printer using the "virtual printer port for USB" I can add the printer seemingly without problem. Once finished, it appears in the Devices and Printers panel. Yet, all attempts to print on this printer fail. It appears that simply no data is sent to the printer (either by programs like word or adobe or by attempting to print a test page. Does anybody know how to fix this?

• Portable Display doesn't work anymore

  - by RipCord

  My USB portable monitor will not work since I installed the hard drive onto an HP laptop. I have installed all the new hardware drivers and do not have any more device issues in device manager view. My old laptop was a lenovo. The new one is an HP. The system seems to recognize devices that I connect via, usb but the portable display still does not show anything on the screen. It is probably a conflict in the registry but I'm not sure how to find it and the Power User does not have the luxury of letting me troubleshoot for hours to isolate the problem.

• How can I disable my laptop's built-in keyboard?

  - by sam

  I have a HP Compaq Presario C700 laptop with Windows 7 installed on it. My laptop's keyboard is not working properly; some keys never work and some keys will keep on pressing. I've formatted the OS but it didn't solve my problem. I bought an external USB keyboard and it works well. As some keys in the built-in keyboard activate themselves, I still couldn't work effectively. After searching Google I tried the following steps to disable the built-in keyboard: Disabled keyboard drivers: This didn't work because when the system reboots, the driver gets installed again automatically. Installed irrelevant driver for keyboard: This failed - I couldn't install the driver. After rebooting it installed the correct driver automatically. Can anyone help explain how I can temporarily uninstall my built-in keyboard? I don't want to remove it manually (removing the hardware cable).

• Making an SSD drive the primary boot/system drive

  - by David Ebbo

  [Not much of a hardware guy, so please excuse my ignorance :)] I just ordered an HP Pavilion Elite HPE-450t (desktop), which came with Win7 installed on the hard drive, using two partitions (C: and D:). Separately, I bought a 128GB SSD that I intend to use as my system drive. I got it in there and connected it, and right now, it's the J: drive (which was the first letter available in disk manager). My goal is for the SSD to get a clean OS install be the C: drive, and to clean out the other hard drive and make it D: (for misc data storage) Question #1: the motherboard has two SATA plugs. Does it matter which one I use for which drive? Question #2: what's the right way to install Win7 on the SSD in a way that it ends up being the C: drive? Do I need to switch some things around in the current Win7 that came with it, are can I do all that while installing Win7 on the SSD?

• Starting VMs with an executable with as low overhead as possible

  - by Robert Koritnik

  Is there a solution to create a virtual machine and start it by having an executable file, that will start the machine? If possible to start as quickly as possible. Strange situation? Not at all. Read on... Real life scenario Since we can't have domain controller on a non-server OS it would be nice to have domain controller in an as thin as possible machine (possibly Samba or similar because we'd like to make it startup as quickly as possible - in a matter of a few seconds) packed in a single executable. We could then configure our non-server OS to run the executable when it starts and before user logs in. This would make it possible to login into a domain.

• Any recommendations on a NAS for a home-super-user?

  - by marc_s

  Can anyone recommend a good NAS for use in a home-server environment? I would request at least 2, preferably 4 disks, and I am most interested in good to excellent throughput for file-server and backup purposes - don't need any of the fancy media-streaming or -sharing features, that's not of interest to me. For a 4 or more disk solution, support for the various RAID levels (0, 1, 1+0, 5) would be a plus - especially if supported in hardware (rather than just a software emulation). I just need a place to put my collection of data, ISO images, and so forth - and since several external disks (self-built and off-the-shelf) have failed so far, I'm looking into a more reliable solution.

• How's the latency with Mac VNC on Windows PC using a crossover cable?

  - by Vadoff

  I use a Windows 8 PC as my main system, and do some programming with Xcode which I use a virtual machine for. However, it doesn't run as smoothly as I would like, so I'm thinking about purchasing a Mac Mini. My question is if I connect my PC to the Mac Mini directly (via crossover cable, firewire, or usb), would I be able to control the Mac using VNC with almost no latency? If not, is there any other way I'd be able to use both my PC and the Mac Mini simultaneously (using the same peripherals)?

• Cannot access Samba Share that is on Linux

  - by doug

  I have 3 virtual machines; Windows Server 2012, Windows 8, and CentOS Linux. The Server is configured with active domain. The CentOS VM has a Samba Share which has rights for the domain Administrator. Now, the Windows Server 2012 DC can successfully locate the share, but cannot access it (with Admin) ? Is it not possible for the Server to have access to it has Domain Client Admin, not Server Admin ? Hope this is clear? Thanks

  When I tried to install libcrypt-ssleay-perl, it says: $ sudo apt-get install libcrypt-ssleay-perl Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libcrypt-ssleay-perl : Depends: perlapi-5.12.4 but it is not installable E: Unable to correct problems, you have held broken packages.

• Installing Windows on multiple computers

  - by Rob

  At our work we've decided to buy SSDs to speed up our computers. We'd also like to upgrade from Windows 7 to Windows 8.1 (read clean install) I'm talking about 10 computers which going to have a fully clean installation. Is there any trick I can use to avoid installing Windows 10 times? The computers (most of them) are different in hardware, so I think duping is no good option. What can I do? I'd like to spend as less time as possible because all computers are going to need SQL Management Studio and Visual Studio 2012/2013. Thanks!

• How to switch off the monitor when mouse reaches the edge of the screen?

  - by evgeny9

  I have 2 computers at home (Windows XP and Windows 7), but one monitor for both of them. They are connected to this monitor using different interfaces: DVI and VGA. I'm also using one keyboard and one mouse to control both PCs with the help of Synergy or Input Director. But I still need to manually switch between monitor interfaces. I wonder, if there's some way (software) that will switch this interfaces (turn off the monitor), when reach the edge of the screen with the mouse. Until now I found several answers, which help to avoid pressing hardware buttons, but still can not do the job automatically based on mouse pointer coordinates. Thank you.

• SNMP - So I have a MIB. Now What?

  - by senfo

  I can't seem to get my head wrapped around the purpose of a MIB. I have a collection of ~20 MIB files that were supplied to me by the vendor, but what do I do with them? I also have a few OID's that were supplied by the vendor that don't seem to be valid. When I issue an "snmpget -v1 -c public 192.168.0.123 .1.4.6.3.2.6.2" (assume that's a valid OID), I get an error indicating the variable is unknown. Does this sound like a hardware configuration problem? Do I need to "load" (for lack of better words) the MIB into the device? Unfortunately, the vendor has been completely unresponsive with returning emails to my questions, so any help would be greatly appreciated.

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do.
