WSUS and the PC's that don't want to report

Ok so below is a direct copy from this website.  It highlights a problem that exisits when imaging multiple PC's from WDS.  Now im not sure if this occurs when the origianl image is made from a PC that is on the domain or not.  I used the VB Script to ease my burden.

5. Imaged clients with a duplicate client ID will only appear once in the WSUS Admin Console. Each AU client must have a unique id which is created for each individual install. When imaging systems it is recommended always to use SysPrep. The WSUS admin console will only display one client for each unique ID. If you have multiple clients created from one image which are sharing the same ID, only one will appear in the WSUS admin console. All clients will check in and download updates, but only one will appear and display status in the WSUS admin console. In cases where clients are not checking in, and they were created from images without running SysPrep, the following steps will reset the existing duplicative client IDs.
a. Run regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate
b. Delete the PingID, SUSClientID and the AccountDomainSID values
c. Stop and start the Wuauserv Service
d. From the command prompt run: wuauclt /resetauthorization /detectnow

or-

From the command line, once you are sure the AU client is properly configured and not disabled, you could run a batch file (which might look something like this sample) and get the same results:

rem Fixes problem with client machines not showing up on the server due to imaging method

reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v AccountDomainSid /f
reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v PingID /f
reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v SusClientId /f
cls
@echo Triggering detection after resetting WSUS client identity
net stop wuauserv
net start wuauserv
wuauclt /resetauthorization /detectnow
Additionally the following VBScript can be deployed via group policy to perform the above function automatically at logon. The script creates a registry key that will allow the script to check if it has been run on that client before. If it has it ends without performing any further changes.

Dim objShell, strKeyPath, strValueName,strComputer
set objShell = wscript.createObject("wscript.shell")
const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objRegistry = GetObject("winmgmts:\\" & strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate"
strValueName = "SUSClientIdReset"

objRegistry.GetStringValue HKEY_LOCAL_MACHINE, strKeyPath, strValueName, dwValue
IF (dwValue = "1") THEN
            'do nothing
      ELSE
            'Fixes problem with client machines not showing up on the server due to imaging method
            objRegistry.DeleteValue HKEY_LOCAL_MACHINE,strKeyPath,"SusClientId"
            objRegistry.DeleteValue HKEY_LOCAL_MACHINE,strKeyPath,"SusClientIdValidation"
   Set colServiceList = objWMIService.ExecQuery ("Select * from Win32_Service where Name = 'wuauserv'")
   For Each objService in colServiceList
    If objService.State = "Running" Then
    objService.StopService()
    Wscript.Sleep 10000
    objService.StartService()
    End If
   Next
 
            objShell.Run("wuauclt /resetauthorization /detectnow ")
   Wscript.Sleep 10000 
            objShell.Run("wuauclt /r /reportnow")
            'Set reg value for SUSClientIdReset for checking against later.
   dwValue = "1"
            objRegistry.SetStringValue HKEY_LOCAL_MACHINE, strKeyPath, strValueName, dwValue
End If

Just save the above scipt as a *.vbs.
