Samba - DHCP & NAT

[Coutts, Ashe]

I am using a Linux box (kernel 2.4.11) with iptables at a high school 
to NAT 172.16.x.x numbers thru it. I am using SAMBA on another 
box. 

Win 9x NATed cpus cannot browse thru their network neighborhood 
and see the Samba server. But one is able to:
"Net Use \\ITS-P3-Server\Tester"
to attach and have access.

Any suggestions would be greatly appreciated.
