powercfg.exe /h off

But what if we wanted to repeat this task for let’s say 30-40 servers? Do it by hand? No way, Powershell to the rescue!
Here’s the script I came up with, enjoy:

# Ask for credentials used to do remote WMI.
$cred    	= Get-Credential DOMAIN\account

# Filter used for active directory query. Only 2008 server machines.
$strFilter 	= "(&(objectClass=computer)(operatingSystem=Windows *2008*))"

$objDomain 	= New-Object System.DirectoryServices.DirectoryEntry
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.Filter = $strFilter
$objSearcher.SearchScope = "Subtree"

$colResults = $objSearcher.FindAll()

# Loop through list of servers.
foreach ($objResult in $colresults)
{
	$objItem = $objResult.Properties
	$name = $objItem.name[0]

	Write-Host "Disabling hibernation on: $name"

	try {
		invoke-wmimethod -cred $cred -path win32_process -name create -argumentlist "powercfg.exe /h off" -ComputerName $name
	}
	catch {
		Write-Host "Failed to disable hibernation on: $name, no permission or server down?"
		break
	}
	finally {
		Write-Host "Hibernation disabled on: $name"
	}
}

Onwards!

This happened after the server (suddenly) ran out of free disk space. It turned out that all color settings where reset to “0″ (black), the registry showed the following color values:

The fix for this was easy, I took the color schema settings from a working 2003 server and inserted them remotely from my workstation. The color schema settings are located under the following registry key: HKEY_USERS\.DEFAULT\Control Panel\Colors

1. Shut down the virtual machine in question.
2. Connect the virtual machine OS disk to another virtual machine, this can be a running virtual machine (please note that you do need to reboot this machine after you are done):- Click edit settings on the running virtual machine.- Click on “Add…” to add hardware to the machine.
   - Select “Hard disk”
   - Select “Use an existing virtual disk”
   - Browse to the virtual disk.
   - Click “Next” and “Finish”

   Your running virtual machine should now look like this:

   

   Click “OK” to apply the settings.

3. Now go to edit settings again, and change the size of the virtual disk.

   Click “OK” once again.

4. Now open the console of the running machine. And start a command prompt.
5. Type “diskpart”.Within diskpart, type “list disk” to display available disks, you should notice the disk with the free space:

   

   Now select that disk, using “select disk 2″ (2 being the disk number offcourse..)
   After that, select the appropriate partition, using “select part 1″ (1 being the partition number)
   

   Now extend the partition using the “extend” command.

   

   Hooray! :-)

6. Now shut down the virtual machine, and remove the added disk. After that you can power on the initial virtual machine.
