GINA is responsible for the login screen that you see (unless you have it set to log you on automatically). It's found in both 2000 and XP. There's a MSGINA, which is Microsoft's version, and there's a NWGINA, which is Novell's version. You might try doing a system restore to a day or two before the problem started happening, or, if that fails, try downloading and reinstalling SP1. Don't forget to reinstall the patches afterwards. --Scott.
