Duplicate computers appear within WSUS

Reading Time: < 1 minute

If you find duplicate computers appearing in wsus, you will need to recreate the susclientid on the duplicate computer. This happens when the same computer is cloned with the same name.

To resolve, copy the below code into a bat file and run.

@Echo off
if exist %systemdrive%\SUSClientID.log goto end
net stop wuauserv
net stop bits
reg delete “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\WindowsUpdate” /v PingID /f  > %systemdrive%\SUSClientID.log 2>&1
reg delete “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\WindowsUpdate” /v AccountDomainSid /f  >> %systemdrive%\SUSClientID.log 2>&1
reg delete “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\WindowsUpdate” /v SusClientId /f  >> %systemdrive%\SUSClientID.log 2>&1
net start wuauserv
wuauclt.exe /resetauthorization /detectnow

exit
