Need a script to find computers missing the UUID in AD

I use the following script to add UUID's to AD for use in Windows Deployment Services (WDS)


for /f %%I IN (
'psexec  \\^%1 cmd /c "echo csproduct get UUID|wmic.exe" ^| ^
findstr /r ........-....-....-....-............ '
) do wdsutil /set-device /device:%1 /id /JoinDomain:Yes /Domain:<DOMAIN NAME>

I have added hundreds of computers to the WDS server with this method.  I now need to find and export to a txt file all the computers in an AD OU that are missing the UUID.

Your help in this matter is appreciated.

This should get what your looking for.

$computers = Get-ADComputer -Filter * | % {
Get-WMIObject -ComputerName $_ -Class Win32_ComputerSystemProduct | Select @{Name="ComputerName";Expression={"$_"}},UUID | Where {$_.UUID -eq $Null -OR $_.UUID -eq ""} | Out-File C:\UUIDMissingReport.txt -append
}

I created a batch file and ran it.  It says that $computers is not recognized as an internal or external command.  Also, how do I target a specific OU on the domain?

I ran this as a powershell script and the file that is created is blank.  

Also, how do I specify the Domain and the OU in the domain to scan?

if the file is blank then you may not have any blank UUID's. To get all of them you can run this.

$computers = Get-ADComputer -Filter * -server "domain.com" -SearchBase "CN=Computers,DC=DOMAIN,DC=COM" | % {
Get-WMIObject -ComputerName $_ -Class Win32_ComputerSystemProduct | Select @{Name="ComputerName";Expression={"$_"}},UUID } | Out-File C:\UUIDReport.txt -append
}

I think what you're looking for is computer accounts that don't have the NetBootGUID set.
Get-ADComputer -Filter {netbootguid -notlike "*"} -SearchBase "ou=someou,dc=domain,dc=com" | Select Name | Out-File results.txt

Great this method is exactly what I was looking for.  Thank both of you for your quick support in this matter.  I am still a powershell novice but I am learning.

footech has it I think, the NetBootGUID...

Interesting way of setting it originally, I plumped for a different approach - it also works with the MAC address in that field for WDS which you can soon get from ARP table, WMI or from log files created during PC startup. in that case set using script for new pC's and rebuilding ones checks if ID in AD, moves to new correct OU and sets the ID from Mac address.

BTW you should be able to do it without PSEXEC too, e.g.

@echo off
for /f "skip=1" %%a in ('WMIC /namespace:%1 CSPRODUCT GET UUID') do (
  echo %%a is now your ID to use with WDSutil etc.
)

Thanks for the additional method Steve Knight,

I did try your script and I am getting "Invalid Global switch"

Odd, you did pass a pc name still? Anyway never mind you are already ok.

WMIC /namespace:otherpcbame CSPRODUCT GET UUID

That should work though.
