Then you've hosed your XP install. XP does not resolve cached addresses
before the hosts file.

Ping your 1918 domain controller. Add a bogus entry for the FQDN of the
same machine. Ping it again. Hosts file overrides. I'm not sure what you
mean by "DNS failiures" though. Please post something we can all use to
test your rotten but unsurprising behavior.

Oh, and before getting very frustrated, even in your hosed install, just try
a "IPCONFIG /flushdns" next time.
