I have a Web-based app that works well on Windows 2000 SP3 after installing SP4 on top of SP3.

A good place to start troubleshooting this type of error is to carefully examine what the app is trying to do when the error condition occurs. I like Filemon, Regmon, and Process Explorer, available from sysinternals.com:
