[Samba] Samba 3 master browser on two networks plus WINS

[Gaiseric Vandal]

WINS is not the issue since you can't connect via IP either.
Routing is not the issue since you can connect to other services.   Are 
all clients showing 5.1 or 7.1 as default gw?

It could be a firewall configuration issue on your server- although that 
does not seem likely.  Did you have to specifically add rules to allow 
HTTPS?  Can you temporarily disable the firewall on the server?

Are their firewalls enabled on the PC's?  Presuming clients don't have 
problems accessing shares from other clients on the same subnet?   The 
default XP firewall behavior may be to block network shares.    I think 
it is possible to configure the XP firewall to allow access from some 
IP's but not others-  but that is something you would have had to 
explicitly set up.

Fedora typically has a firewall enabled as well-   on fedora you have 
the "system-config-firewall" command to provide a gui front end (I think 
this is iptables.)  It may have specific ports and services enabled or 
disabled by default but I don't think it would have rules that filter by 
source ip enabled by default.

Can you "telnet somehost 139" ?
