You'll have to check the archives for details I'm afraid. This might apply to you. If you're happy that doesn't affect you then I'd look at the disk system - perhaps XP has newer drivers than Win2k. What do the MS performance-charts show is happening? Specifically, CPU and disk I/O. -- Richard Huxton Archonet Ltd
