WSUS Troubleshooting

The information below is concerning the Windows Update process and a WSUS service on the backend.  To manually start the process to have a Windows client to check for new updates, run this command at the command prompt:

 wuauclt.exe /detectnow

If new updates to not appear to be downloaded, open the following file and check for errors.

%SystemRoot%\windowsupdate.log

One procedure to use if updates are not “flowing” is to stop the automatic updates service, delete the %SystemRoot%\softwaredistribution folder, start automatic updates service, run wuauclt.exe /detectnow and wait about 10 minutes.

Another procedure would be to at a command prompt run:

regsvr32 /u wuaueng.dll

Delete the folder %SystemRoot%\softwaredistibution

Delete %SystemRoot%\windowsupdate.log

At a command prompt run:

 regsvr32 wuaueng.dll

At a command prompt run:

 net start wuauserv

At a command prompt run:

wuauclt.exe /resetauthorization /detectnow

Another possibility is to download an updated client.  Details can be found at:

When updating the local client, the following command line parameter may be used to force the installation:

WindowsUpdateAgent30-x86.exe /wuforce

The SUSID is how WSUS identifies each and every system in it's environment.  The path within the Registry for this information is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\SusClientId

If a computer is being cloned, the key above may need to be deleted so the new machines are displayed as separate items within the WSUS console.
