There have been reports of very slow network performance on Win2k systems
with the default configuration. 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.
