Duplicate computer entries

I have several client computers (all running Windows XP Pro) that appear 2 or
3 times in the "Computers" list on my WSUSAdmin console. Does anyone know why
this happens, how I can prevent it in the future, and how I can clean it up?

My WSUS server is running on Windows Server 2003.

Thanks!

Hi,

The identifier that WSUS uses to identify a computer is the data
in the registry value SusClientId under the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\WindowsUpdate

If you have deleted this registry value on a computer that already
have connected to the WSUS server, or you have re-imaged the
computer after it have connected to the WSUS server, you will end
up with duplicate computer entries.

You can just delete the entries that have the oldest reported date,
or use the CleanStaleComputers program to delete computer entries that
haven't contacted the WSUS server for x days (you decide what x is).

The CleanStaleComputers tool is in the "Windows Server Update
Services API Samples and Tools" available for download here:
