Problems mapping net drive to samba folder

[Yair Zohar]

Hello,
I have installed a new linux 6.0 server, using samba 2.0.3
The net is divided to two IP subnets which only TCP IP can pass
between them.
Users (win95/98) that use the same subnet as the server can map
a network drive to a samba folder by supplying thier linux password,
but users on the other subnet can't, they are asked for a password
when they try to map the drive, but the mapping fails.

any suggestions ?
Thanks
Yair
