I was having this problem and find a fix here: http://www.computing.net/windows2000/wwwboard/forum/42735.html
This problem is caused by the addition of Windows Update Hotfix Q329170 if you have SP3. Verification is seen in the event viewer "application log", the error being "usernv" "Windows cannot uload your registry file..........". It seems to be a function of the order in which SP3 and pre sp4 hotfixes are installed. Removing q329170 solves the problem, but slightly increases security risks in a business network where users could be risks. I see no problems on a home network. Curiously, Microsoft has not yet acknowledged this problem, which is reasonably widespread.
