might take a look at /etc/hosts.conf,

make sure all your local hosts are in /etc/hosts and specify
"order hosts bind" in /etc/hosts.conf.

also, make a hosts file for the winders machines, or specify the
linux server as a WINS server. win32 will usually check WINS and
then DNS even for local hosts.
