I assume they're DHCP. Are you using WINS, and is it functioning properly?
NBTSTAT -c will tell you a lot about what the PC is resolving. Also, what
are you using as a default gateway? We had a checkpoint firewall at my last
job, and pointed all PCs to that as a default. Turns out the CP didn't pass
directed broadcasts, which made logging into certain domains impossible on
just 95/98. Pointing everything to the Cisco router fixed it. HTH.
