You didn't specify what rule is logging this traffic. Is it your default
drop rule or something earlier?
Try this on the XP box the next time queries start to fail:
ipconfig /flushdns
If you now start working fine, your DNS is just running slow and XP is
caching negative entries. Make the following reg key change:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
DWORD: MaxNegativeCacheTtl
Value: 0
Reboot and you should be all set.
HTH,
Chris
