Essentials 2007: How to Enable Windows Update debug logging
Awhile back, I posted some troubleshooting steps for a problematic Automatic Updates Client (find that post HERE)
Here is one additional item - enabling debug logging for the client. In many cases, it may only be useful to the Essentials 2007 / WSUS support teams, but will generate good info to bring along when posting a problem.
To enable Windows Update debug logging perfom the following. Verbose output goes to the%windir%\windowsupdate.log file.
a. Open regedit and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate
b. Create a New Key called Trace
c. In Trace, create a new DWORD value called Flags with a Data of 7
d. In Trace, create a new DWORD value called Level with a Data of 4
e. Close regedit
2. Navigate to %windir%, find the file named ‘WindowsUpdate.log’, rename it to ‘WindowsUpdate.old’.
3. Restart the Automatic Updates server and run the ?wuauclt /detectnow? command to force an update detection cycle.
