Windows Small Business Server (Windows SBS) Update Services is not running because it automatically turns off if you customize Windows Server Update Services (WSUS).

Problem:  In the Server Management Panel of SBS 2003 the server is reporting that update services are not running because it automatically turns off if you customize Windows Server Update Services.

Solution: This message was a pain to troubleshoot because at first glance the settings were not altered.  However, if you installed WSUS 3.0 (update services 3 upgrade) you can replicate the same issue.

This is the link to the correct Microsoft solution for resolving this issue: http://support.microsoft.com/?kbid=945985

Use Method #1, after applying Steps 1-4 and confirming the update service is running, return to Server Management > Update Services and click “refresh”

If you receive a Bad Request error, then your Internet Information Service for the default site is not running.. Go to Server Management > Advanced Management > Internet Information Service > Server > Web Sites >  Default Web Site  – Ensure the IIS is running for that site.
