Just one suggestion ...
- if you are using DHCP, manually set an IP of one of them outside of
the DHCP range and see if you are having the same issue.

And some questions ...
-- can they ping each other by name, or only by IP address?
-- is the same device giving out addresses?  Perhaps are BOTH devices
running DHCP and getting confused?
-- Is the problem universal, or restricted to devices trying to talk
across the wireless AP to the wired switch?
-- Do the W2000 and XP systems behave differently?
-- when you futz'ed with the configs on the devices, did you see any
settings related to NETBIOS, DNS, or file sharing  that perhaps you
changed trying to make the old address scheme work?

Name resolution in Windows  is kind of weird.  If you let is all run a
few days it sometimes straightens itself out as caches expire, etc.

Good luck!
