We've been running into similar problems here at a major university. Here's
some things we've tried, unfortunately we haven't had much luck with it.
Perhaps it'll help you out.
- Disable IPv6
- Resetting the Winsock catalog
* Note: command 'netsh winsock reset' used
- Resetting the TCP/IP stack
* Note: command 'netsh int ip reset' used
Our problem seems to go in and out every 30 minutes, like yours XP and other
operating systems aren't effected. Our network engineer mentions that the
clients are only talking on their local subnet UDP, no TCP. Very frustrating
issue.
