for the 2000 version of msconfig, which is what allows you to view what is booting with the pc, you need to download StartUpCPL.exe. You can get it at
Freeware files, utilities, anti-spyware tools, & nifty toys with some rudimentary instructions on what happens when you run the .exe. Basically, a new entry is put in your control panel called startup, and that will allow you to add/remove apps from several different directories of startup, including the registry.
I keep that on a usb key,. as the environment I work in is about 40% win 2k, and it really comes in handy.
thanks,
