Then I misread the diagram, sorry.  Start from the top again please -
You have a linux samba server - please post the smb.conf file.  Also -
are you using a wins server?  I had some odd connection problems
(don't recall the details, it was a while back) until I set one up -
on the samba server, as it happens.  You have windows workstations
(Pro or home? Networks in XP home is severly broken.) that are
connecting to the samba server intermittantly.  Can you post the samba
log from a session when the connect fails, and when the connect works?

Have I got the basics straight?

I think you've about got it, now. And my LAN is up today--two days in a row. I've done nothing, that I know of, to achieve this. And some clarifying data that, as my meager knowledge grows, may in fact be relevant. I say that the Linksys sits on the edge of my LAN and everything happens behind it, and that's the intent. However, all three NICs are on the SUSE Samba server, and because of the way YaST works, all three NICs have as their default gateway the Linksys. My understanding is that default GWs are addresses of last resort, so my claim that everything is happening behind the Linksys here stands (e.g., IP Forwarding is on, the stack knows where the interfaces are, etc), but I could be wrong. The smb.conf file (I've included only the global part, as the shares wouldn't seem relevant to this problem) and log excerpts are below.

I have wins support = yes; and I have 2 instances of winbindd running.

I have win2k Pro and XP Pro installed on the two devices. No "Home" versions for me.

Thanks
