Hi All,

I've got several hundreds of Windows Server 2003 and 2008 virtual machine + several physical machine which is updated by WSUS automatically but it needs to be restarted manually.

Is there any way to know which server needs restart and which one is not ?( eg using powershell)

Thanks

For Windows 2003 server you'll need to check "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
> Manager\PendingFileRenameOperations".

One sample script which wa used for windows 2003 server:
<script>
On Error Resume Next

Const HKEY_LOCAL_MACHINE = &H80000002
Const REG_MULTI_SZ = 7

strComputer = "."

Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")

strKeyPath = "SYSTEM\CurrentControlSet\Control\Session Manager"
strValueName = "PendingFileRenameOperations"

oReg.GetMultiStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,arrValues

If Not IsNull(arrValues) Then
For Each strValue In arrValues
Wscript.Echo strValue
Next
Else
Wscript.Echo "No Pending Reboot"
End If

</script>

Also for Server patch reboots please check the following page: http://blogs.msdn.com/b/hansr/archive/2006/02/17/patchreboot.aspx

ah yes, this is the code that i test and it works for me, now it's my turn to modify this script so that it can work for multiple server entry.
function Get-PendingReboot($computer = '.') {
	$hkey		= 'LocalMachine';
	$path_server	= 'SOFTWARE\Microsoft\ServerManager';
	$path_control	= 'SYSTEM\CurrentControlSet\Control';
	$path_session	= join-path $path_control 'Session Manager';
	$path_name	= join-path $path_control 'ComputerName';
	$path_name_old	= join-path $path_name 'ActiveComputerName';
	$path_name_new	= join-path $path_name 'ComputerName';
	$path_wsus = ‘SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired’;

	$pending_rename	= 'PendingFileRenameOperations';
	$pending_rename_2	= 'PendingFileRenameOperations2';
	$attempts	= 'CurrentRebootAttempts';
	$computer_name	= 'ComputerName';

	$num_attempts	= 0;
	$name_old	= $null;
	$name_new	= $null;

	$reg= [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($hkey, $computer);
	
	$key_wsus = $reg.OpenSubKey($path_wsus);
	if ($key_wsus -ne $null) {
		$wsus_values	= @($key_wsus.GetValueNames());
		if ($wsus_values) {
			$wsus_rbpending = $true
		} else {
			$wsus_rbpending = $false
		}
			$key_wsus.Close() | out-null;
	}
	
	if ((($session_values -contains $pending_rename) -or ($session_values -contains $pending_rename_2)) `
	-or (($num_attempts -gt 0) -or ($name_old -ne $name_new)) `
	-or ($wsus_rbpending)) {
		return $true;
	}
	else {
		return $false;
	}

	$key_session	= $reg.OpenSubKey($path_session);
	if ($key_session -ne $null) {
		$session_values	= @($key_session.GetValueNames());
		$key_session.Close() | out-null;
	}

	$key_server	= $reg.OpenSubKey($path_server);
	if ($key_server -ne $null) {
		$num_attempts = $key_server.GetValue($attempts);
		$key_server.Close() | out-null;
	}

	$key_name_old	= $reg.OpenSubKey($path_name_old);
	if ($key_name_old -ne $null) {
		$name_old = $key_name_old.GetValue($computer_name);
		$key_name_old.Close() | out-null;

		$key_name_new	= $reg.OpenSubKey($path_name_new);
		if ($key_name_new -ne $null) {
			$name_new = $key_name_new.GetValue($computer_name);
			$key_name_new.Close() | out-null;
		}
	}

	$reg.Close() | out-null;

	if ((($session_values -contains $pending_rename) `
	-or ($session_values -contains $pending_rename_2)) `
	-or (($num_attempts -gt 0) -or ($name_old -ne $name_new))) {
		return $true;
	}
	else {
		return $false;
	}
}

but if you specify OFFLINE server, it gets ERROR message like:
Exception calling "OpenRemoteBaseKey" with "2" argument(s): "Attempted to perform an unauthorized operation."
At :line:22 char:55
+ 	$reg= [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey <<<< ($hkey, $computer);

Hi, I'm using Nagios to monitor tons of things on my linux+windows servers, including if WSUS patches are waiting to be applied *AND* when the computer needs to reboot.
Here it is:

create a script.wsf with this content (see attached)

It'll return a window with a message or a return code a and message you can get: "Reboot required"



I hope it'll help

Let say, if you already have nagios in place or plan to have it, you'll easily use this script to detect your WSUS status in your monitoring.
But if you don't have it, you could for example run it with psexec (look for it at MS's site, formerly sysinternals) to script something on all your servers

1) Create a check_all_servers.bat with this in it:
@echo off
set ComputerList=myserver1 myserver2
for %%a in (%ComputerList%) do @call check_one.bat %%a
pause

2) In check_one.bat, you'll put:
@echo off
echo Checking server %1
psexec \\%1 -u admin_login -p his_password c:\windows\system32\cscript.exe /NoLogo /T:120 c:\check_windows_updates.wsf /w:0 /c:1
REM provided the .wsf script is named and placed here: c:\check_windows_updates.wsf

3) Run the check_all_servers.bat

I tested it all, some of my servers don't want to start the .wsf, I don't know why. I did not investigate further as it works for most of them.
