[Samba] Newbie Questions--Firewalls

[vze5bgzj]

Hello.

We are running individual software firewalls (as provided by the 
respective OSs) on:

MAC OSX Panther
MSWindows XP Pro
SuSE 8.2 LINUX

Machines.  In addition, the MSWindows XP Pro machine is running 
Norton's Software Firewall (in conjunction with Antivirus version 
10.0.1.13) I am trying to configure SAMBA 2.2.8a from the SuSE LINUX 
system and am unable to see either the MAC OSX Panther or MSWindows XP 
Pro systems across the Network View for SAMBA provided by KDE 3.1.5.  
Neither can I see the LINUX System or the MSWindows XP Pro system from 
the MAC OSX Panther machine.

We are using a Linksys BEFSR41 Etherswitch for LAN Network Connectivity.

Anyone have any ideas what the problem(s) might be?

Thanks

Mike
