• Can't boot up computer windows 8 installation

  - by danny ramirez

  I wanted to install Windows 8 with a volume partition and when the Windows 8 was installing it rebooted and it gave me an error: The digital signature for this file couldn't be verified. File :windows \system 32\winload.exe error code 0xc0000428. I have tried bootec commands and they didn't seem to fix it. Also my Windows 7 got deleted and I only have to boot with the Windows 8 error, so I can't do anything not even boot to safe mode. I have tried to install Windows 8 from disk later on and it won't let me because it keeps rebooting and starting the installation again, so I took off the disk before it rebooted and it takes me to that error again. Remember that's my only boot option so I'm stuck in the installation disk.

• How to use BCDEdit to dual boot Windows installations?

  - by Ian Boyd

  What are the bcdedit commands necessary to setup dual boot between different installations of Windows?5 Background i recently installed Windows 8 onto a separate hard drive1. Now that Windows 8 in installed i want to dual-boot back to Windows 7. i have my two2 hard drives: So you can see that i have my two disks, with the partitions containing Windows: Windows 7: \\PhysicalDisk0 (partition 03) Windows 8: \\PhysicalDisk2 (partition 1) What i'm trying to figure out how is how to use bcdedit to instruct the thing that boots Windows that there is another Windows installation out there. Running bcdedit now, it shows current configuration: C:\WINDOWS\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=\Device\HarddiskVolume2 description Windows Boot Manager locale en-US inherit {globalsettings} integrityservices Enable default {current} resumeobject {ce153eb7-3786-11e2-87c0-e740e123299f} displayorder {current} toolsdisplayorder {memdiag} timeout 30 Windows Boot Loader ------------------- identifier {current} device partition=C: path \WINDOWS\system32\winload.exe description Windows 8 locale en-US inherit {bootloadersettings} recoverysequence {ce153eb9-3786-11e2-87c0-e740e123299f} integrityservices Enable recoveryenabled Yes allowedinmemorysettings 0x15000075 osdevice partition=C: systemroot \WINDOWS resumeobject {ce153eb7-3786-11e2-87c0-e740e123299f} nx OptIn bootmenupolicy Standard hypervisorlaunchtype Auto i cannot find any documentation on the difference between Windows Boot Manager and Windows Boot Loader. Documentation There is some documentation on Bcdedit: Technet: Command Line Reference - Bcdedit Technet: Windows Automated Installation Kit - BCDEdit Command Line Options Whitepaper - BCDEdit Commands for Boot Environment (Word Document) But they don't explain how edit the binary boot configuration data If i had to guess, i would think that a Windows Boot Manager instructs the BIOS what program it should run. That program would give the user a set of boot choices. That leaves Windows Boot Loader do be a particular boot choice, that represents a particular installation of Windows. If that is the case i would need to create a new Windows Boot Loader entry. This means i might want to use the /create parameter: /create Creates a new boot entry: bcdedit [/store filename] /create [id] /d description [/application apptype | /inherit [apptype] | /inherit DEVICE | /device] So i assume a syntax of: >bcdedit /create /d "The old Windows 7" /application osloader Where application can be one of the following types: Apptype Description BOOTSECTOR The boot sector application OSLOADER The Windows boot loader RESUME A resume application Unfortunately, the only documentation about osloader is "The Windows boot loader". i don't see how that can differentiate between Windows 8 on one hard drive, and Windows 7 on another. The other possible parameter when /create a boot loader is >bcdedit /create /D "Windows Vista" /device "The Quick Brown Fox" Unfortunately the documentation is missing for /device: /device Optional. If id is not set to a well-known identifier, the option that is used to specify the new boot entry as an additional device options entry. Since i did not set id to a well-known identifier, i must set /device to "the option that is used to specify the new boot entry as an additional device options entry". i know all those words; they're all English. But i have on idea what it is saying; those words in that order seem nonsensical. So i'm somewhat stymied. i don't want to be like Dan Stolts from Microsoft: I found no content that was particularly helpful when I hosed my machine by playing with BCDEdit. This post would have been ok if there was much more detail especially on the /set command OSDevice, etc. So once I got my machine fixed, I documented the solution and the information is here.... i mean, if a Microsoft guy can't even figure out how to use BCDEdit to edit his BCD, then what chance to i have? Bonus Reading BCDEdit Command-Line Options Bcdedit Server 2008 R2 or Windows 7 System Will NOT Boot After Making Changes To Boot Manager Using BCDEdit Visual BCD Editor4 Windows 7 and Windows 8 RTM Dual Boot Setup Footnotes 1 Since the Windows 8 installer would have damaged my Windows 7 install, i decided to unplug my "main" hard drive during the install. Which is a long-winded explanation of why the Windows 8 installer didn't detect the existing Windows 7 install. Normally the installer would have automatically created the required entries for dual-boot. Not that the reason i'm asking the question is important. 2 Really there's three drives, but the third is just bulk storage. The existence of a 3rd hard drive is irrelevant to the question. i only mention it in case someone wants to know why the screenshot has 3 hard drives when i only mention two. 3 i arbitrarily started numbering partitions at "zero"; not to imply that partitions are numbered starting at zero. i only mention partitions because i don't see how any boot-loader could do its job without knowing which partition, and which folder, an installation of Windows is located in. 4 i'm asking about BCDEdit. i tried Visual BCD Editor. It seems to be a visual BCD editor. That is to say that it's a GUI, but still uses the same terminology as BCDEdit, and requires the same knowledge that BCD doesn't document. 5 For simplicity sake we'll assume that all installation of Windows i want to dual-boot between are Windows Vista or later, making them all compatible with the BCDEdit and the binary boot loader. The alternative would require delving into the intricacies of the old ntloader. Nor am i asking about dual booting to Linux; or how to boot to a Virtual Hard Drive (vhd) image. Just modern versions of Windows on existing hard drives in the same machine. Note: You can ignore everything after the word Background. It's all pointless exposition to satisfy some people's need for "research effort" before they'll consider being helpful. Some people have even been known to summarily close questions unless there is research effort. Some people have been know to close questions if there is too much research effort. Some people close questions when i put the note saying that they can ignore everything after the Background out of spite. Some people are just grumpy.

• Why do I get Access Denied when using WinRM?

  - by Kev

  Following on from this question: Why does my PowerShell script hang when called in PSEXEC via a batch (.cmd) file? I took the advice from Jim B and installed WinRM. To recap I have two servers: HMon01 - runs Windows 2003 Standard SP2 Web1928 - runs Windows 2008 Standard SP2 Both servers are standalone. I installed WinRM for Windows 2003 from here and configured WinRM as follows on both machines: Client NetworkDelayms = 5000 URLPrefix = wsman AllowUnencrypted = false Auth Basic = true Digest = true Kerberos = true Negotiate = true Certificate = true DefaultPorts HTTP = 80 HTTPS = 443 TrustedHosts = * The problem I have is that if I remotely execute commands using the remote machine's built in Administrator account then all is well. However I have an account on the remote machine named remoteexec which is a member of the Administrators group (we disable our Administrator accounts). If I use this account then I get Access Denied errors. I've done all the usual things such as checking passwords and the like. Why would this be?

• Need help with executing and deleting remote bash script via a local bash script

  - by kenja

  I am trying to create a bash script that will scp a script to a remote server, ssh (using an ssh key that is already installed) to the remote server, execute the uploaded script, and then delete the remote script when it is finished. I'm not clear how to run an ssh session inside a bash script. Here are the commands I use to do it from the command line: scp my_script.sh [email protected]:/usr/home/user/ ssh [email protected] >sh my_script.sh >rm myscript.sh >exit How do I script the ssh portion of my command list? Thanks!

• IIS7 Network Bios command limit and disabling file change notifications.

  - by meandmycode

  Having experienced IIS for many years I've hit this error various times in the past, and understand it, the gist being IIS is attempting to setup so many file change notifications over a UNC share that it is hitting a specified limit of active commands. However, whilst I understand this is a registry change on the endpoints, in our internal network we're starting to hit this when running certain domains that have large content (and the content is then stored out of source control and instead on a dumb network store). Given this is a testing environment and rather than changing registry settings (which may not even work for client (dev) machines that run Vista IIS), I'd like to stop IIS setting up all these file change notifications. Is this possible to do on a per site basis? additionally the configuration can't be in the web.config, if this means having to disable FCN's for the entire IIS server this would be preferred. Thanks in advance.

• How do I mount an EBS root volume to a windows instance in Amazon EC2

  - by Kyle

  So basically, I created a large windows server for development, and then I created a micro windows server for production. I set up everything how I wanted it on my development server, and then i unmounted the drives, and mounted them to my micro server. Now I'm trying to get back into my large windows development server, and I'm getting the error. Invalid value 'i-4896ce28' for instanceId. Instance does not have a volume attached at root (/dev/sda1) this error pops up when I try to start my large windows server. I've remounted the drives to the large development server, and I still get this message. I'm not really sure what to do, I've read other posts and everyone is giving these almost like command line arguments and talking about other tools, and I really have no clue what any of that means, or where I even have an option to enter any commands without be logged into a specific instance.

• PowerShell Remoting w/ Exchange 2010

• HP Loadrunner failed to start .NET Diagnostics probe

  - by Johnbo

  I've got a HP Diagnostics Server (commander mode) installed in the same PC where HP Loadrunner is. I've installed the .NET probe in the web application server. When I navigate localhost:2006/registrar/health I can see the CommandingServer and three instances of the probe, all in green and connected. Then, when in LoadRunner controller I enable Diagnostics, select the probe and start the scenario, I get the next error: Failed to start J2EE/.NET Diagnostics run. (Facade error: Unable to send 'startRun' notification to probe MyAgent.1347615505142149) I've looked at the firewall logs and the rule that lets the server send commands to the probes has been matched three times. What else could it be what doesn't let me start the probe?

• Creating a user account on a mac you don't have admin access to [migrated]

  - by mouse

  I am trying to create a user account on a school computer so I can run processes (like compiling large libraries) with admin permissions settings. This way I can walk away and let other people user the computer, and come back after class to retrieve the binaries. Usually some smart person decides to shut the machine down, but if I had higher permissions they wouldn't be able to terminate my processes. Right now I use the guest account, which everyone has access to. If you think this is in some way unethical or a bad idea, please criticize. tl,dr I tried using the dscl series of commands in single user mode as root, as recommended by this site. It returns this error: Cannot open remote host, error: DSOpenDirServiceErr How can I create a local user on this machine to compile my code with higher permissions?

• Using VLC as RTSP server

  - by StackedCrooked

  I'm trying to figure out how to use the server capabilities of VLC. More specifically, how to export an SDP file when RTP streaming. In chapter 4 in the section related to RTP Streaming examples for server and client are given: vlc -vvv input_stream --sout '#rtp{dst=192.168.0.12,port=1234,sdp=rtsp://server.example.org:8080/test.sdp}' vlc rtsp://server.example.org:8080/test.sdp It's not very clear to me how to make it actually work. I have tried these two commands for server and client using two cmd instances: vlc -I rc screen:// --sout=#rtp{dst=127.0.0.1,port=4444,sdp=rtsp://localhost:8080/test.sdp} vlc -I rc rtsp://localhost:8080/test.sdp Invoking the second command causes the first one to crash. The second command shows the error message "could not connect to localhost:8080".

• SQL 2008 Database tuning advisor won’t start

  - by Andrew Hancox

  For some reason I can't get DTA to connect to my development machine. It connects to a remote DB just fine but when I point it to my dev machine I get an error saying: Failed to initialize MSDB database for tuning (exit code: -1073741819). I'm pretty sure it's not a permissions issue since I've used profiler to capture what it's doing and all of the commands it's run so far look fine and are being run under my account which is associated with the sysadmin role, when I run them in sql management studio they go through fine. I'm pretty convinced that the problem is related to creating the objects in MSDB that are used by DTA but I tried creating these manually (I found scripts on the web) and it just seems to push the problem along the line slightly. I'm going out of my mind - have even tried reinstalling SQL but that's not fixed it. I'm using SQL 2008 with SP1 (10.0.2531) on windows server 2008 (patched up to date). SAVE ME!!!!!

• What's the most efficient way to reclaim disk space after deleting lots of data from a database on Sybase ASE 15?

  - by Ernie Longmire

  As I understand it, based on some research but zero real-world experience with Sybase ASE, the only way to reclaim disk space once it's been allocated to a database is to export that database, create a new DB with the same schema, and reload all the exported data to the new database. Is this correct, or is there some other method? Then: assuming the above is correct and a full export-recreate-reload is required, what's the most efficient way to do that? Are there tools that will automate all or part of that process? I'm being told we would have to write separate bcp export and import commands for each and every object in the database, which if true sounds easily scriptable by someone who knows Sybase ASE well enough. (I don't.) This seems to me like a really basic housekeeping task, and it feels like I'm missing something obvious.

• Problem using psexec to remotely GAC a file

  - by Andrew Dunaway

  As part of a deployment process I am trying to GAC a series of files. The actual build process occurs on a build server, and I am trying to use psexec to GAC the files on whichever machine has requested the build. The current line I am trying to execute is: C:\PsToolspsexec.exe \COMPUTER -u USER -p PASS gacutil.exe -i Assembly.dll -f The error that I am getting back is: Failure adding assembly to the cache: The system cannot find the file specified. So apparently the dll reference is on the remote box, and unfortunately the dll is sitting on the build box. Is there any way to just do this with psexec somehow, or do I need to copy it to some temporary location on the \\COMPUTER? I know there are commands to copy the executable as part of the psexec process, but I can't seem to find anything similar for supporting files.

• How to make computer interface with circuit

  - by light.hammer

  I understand that I can build a circuit that will do whatever I like (ex: a simple circuit that will turn on a motor to open the blinds or something), and I can write a program that will automate my computer/mac however I like (ex: open this program at this time, or with this input and create a new file, ect). My question is, how can I interface the two? Is there an easy DIY or cheap commercial (or not cheap but functional) USB plug that will turn on/off from computer commands? I'm basically looking for some sort of on/off switch I can script/applescript. How would you even approach this problem, would I have to write my own driver some where along the way?

  I have the following class: public class Day { public int Date { get; set; } public String DayName { get; set; } public Day() { } public Day(int date, string dayName) { Date = date; DayName = dayName; CommandManager.RegisterClassCommandBinding(typeof(Day), new CommandBinding(DayClick, new ExecutedRoutedEventHandler(OnExecutedDayClick), new CanExecuteRoutedEventHandler(OnCanExecuteDayClick))); } public static readonly RoutedCommand DayClick = new RoutedCommand("DayClick", typeof(Day)); private static void OnCanExecuteDayClick(object sender, CanExecuteRoutedEventArgs e) { ((Day)sender).OnCanExecuteDayClick(e); } private static void OnExecutedDayClick(object sender, ExecutedRoutedEventArgs e) { ((Day)sender).OnExecutedDayClick(e); } protected virtual void OnCanExecuteDayClick(CanExecuteRoutedEventArgs e) { e.CanExecute = true; e.Handled = false; } protected virtual void OnExecutedDayClick(ExecutedRoutedEventArgs e) { string content = String.Format("Day {0}, which is {1}, was clicked.", Date.ToString(), DayName); MessageBox.Show(content); e.Handled = true; } } I am using the following DataTemplate (that is in a ResourceDictionary) to render it: <DataTemplate DataType="{x:Type local:Day}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Rectangle Grid.ColumnSpan="2" x:Name="rectHasEntry" Fill="WhiteSmoke"/> <TextBlock Grid.Column="0" x:Name="textBlockDayName" Text="{Binding DayName}" FontFamily="Junction" FontSize="11" Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/> <TextBlock Grid.Column="1" x:Name="textBlockDate" Text="{Binding Date}" FontFamily="Junction" FontSize="11" Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/> <Rectangle Grid.ColumnSpan="2" x:Name="rectMouseOver" Fill="#A2C0DA" Opacity="0" Style="{StaticResource DayRectangleMouseOverStyle}"> </Rectangle> </Grid> </DataTemplate> No problems so far, I can get it on screen. What I want to be able to do is assign a Command, or use an event, so that when the user clicks on the Day it will notify the parent of the Day object that it has been clicked. I've tried the following: <Rectangle.CommandBindings> <CommandBinding Command="{x:Static local:Day.NextDay}" Executed="{x:Static local:Day.OnExecutedDayClick}" CanExecute="{x:Static local:Day.OnCanExecuteDayClick}"/> </Rectangle.CommandBindings> to try and bind the commands that are in the Day class but it didn't work. I got an error stating: 'ResourceDictionary' root element requires a x:Class attribute to support event handlers in the XAML file. Either remove the event handler for the Executed event, or add a x:Class attribute to the root element. Which I think means that there is no code-behind file for a ResourceDictionary, or something to that effect. In any event, I'm not sure if I should be using Commands here, or somehow tying events to the Rectangle in question, or if this is even possible. I've seen various places where it sure looks like it's possible, I'm just unable to translate what I'm seeing into something that actually works, hence this post. Thanks in advance.

• How can I make check_nrpe wait for my remote script to finish executing?

  - by Rauffle

  I have a python script that's being used as a plugin for NRPE. This script checks to see if a process if running on a virtual machine by doing an SSH one-liner with a "ps ax | grep process" attached. When executing the script manually, it works as expected and returns a single line of output for NRPE as well as a status based on whether or not the process is running. When I attempt to run the command setup to execute this script (from my Nagios server), I instantly get the output "NRPE: Unable to read output", however when I run the script manually it takes about a second before it returns output. Other commands run just fine, so it would seem like NRPE needs to wait a second or two for output rather than instantly failing, but I've been unable to find any way of accomplishing this; any tips? Thanks PS: The virtual machines are not accessible from anywhere other than the host machine, hence the need for the nrpe plugin to ssh from the host into the VM to check the process.

• Make bootable iso with grub chainloading

  - by hlovdal

  My parents' pc has windows 7's boot manager installed at MBR and grub2 is installed on /dev/sda2 (booting linux on /dev/sda2). I want to make a bootable cd so that when booted from it just chainloads into the boot manager on the second partition. I assume using grub rather than grub2 for this will be simpler, using the configuration timeout=0 hiddenmenu default=0 title grub2 (/dev/sda2) rootnoverify (hd0,1) chainloader (hd0,1)+1 I know I can make a bootable linux cd in various ways, but that is not what I want. I just want to put grub/grub2 on the cd, no kernels or programs. The question is how do I make the iso file? I have found some references to installing on a floppy or usb disk, but all those assume the device is present when running the grub install commands. A iso file is different.
