Then I misunderstood that. But this isn't a problem, because then it's 
clear, that you don't want to listen Samba on that interface for sure.

interfaces = lo eth0
to your smb.conf and restart Samba (replace eth0 if this isn't your 
internal NIC). Let Samba listen on all interfaces (+ loopback), you want 
to serve to.

How are the others connected to the internet? Is it the same than the 
problem-box (one NIC to LAN, one NIC to I-Net)? And is their Internet 
connection the same (wireless or is it stable and wired)?

If the clients can still resolve their own domain stuff, it should work. 
You can configure the problem-box to forward DNS requests to one of your 
working hosts. Then exclude this.

What version of Samba do you run? If 4, do you run it in AD mode or 
NT4-style? Samba 4 in AD mode, doesn't have Netbios browsing (network 
neighbourhood) yet:
