Troubleshooting Automatic Updates with WSUS

Here are a few troubleshooting steps which can help you to resolve issues related to Automatic Updates with WSUS.

1. For clients in a domain environment, ensure the Automatic Update Policies specified in WUAU.ADM have been applied. You can use GPRESULT.EXE against the Windows client compWuter to see the applied policies (download GPRESULT.EXE from the Microsoft web site). Additionally, you can use the Group Policy Management Console to ensure the AU related policies have been applied.

2. For clients in a a workgroup environment, configuration is via the registry or via local policy.

3. Confirm the the client's AU settings and ensure they are set the way you intend. A simple way is to use the REG.exe command to dump out the policy settings from the client's registry. Use the following syntax:

Reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /s

You should see something like this:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
WSUServer REG_SZ http://dc1.nwtraders.msft
WSUStatusServer REG_SZ http://dc1.nwtraders.msft

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
NoAutoUpdate REG_DWORD 0x0
AUOptions REG_DWORD 0x3
ScheduledInstallDay REG_DWORD 0x0
ScheduledInstallTime REG_DWORD 0x3
UseWSUServer REG_DWORD 0x1
DetectionFrequencyEnabled REG_DWORD 0x1
DetectionFrequency REG_DWORD 0x1

4. Check that the Automatic Update client code has been updated to use WSUS.
Check the file version for the files Wuauclt.exe and Wuaueng.dll (both are in your %systemroot%\system32 folder). Both should be version of 5.4.3790.1851 or later.
