Hello all
I am also posting this question to the Windows 2k discussion board
We have an AIX Server running Samba 2.2 (IP:172.17.2.42). We can browse and map share folders on this computer if we do it from our LAN (172.17.x.x). We also can browse (Using My Network Places) the server from remote locations (172.22.x.x). However, we are unable to map a share folder on the AIX machine. We analyze the connection with a sniffer, and for some reason the remote computer try to connect to the AIX machine using ports 445 (we know this is ok), but then it does not try to use port 139, which is the port used by samba (Which corresponds to pre-win2k machines). The remote location is connected with tha main site trought a fiber optic link with a router and a firewall in the middle. The firewall has ports 137,138, and 139 enabled
Thanks in advance for your help
Néstor.
 
When NetBIOS over TCP/IP is disabled on W2k and later clients, then only the
TCP port 445 will be used.
If NetBIOS over TCP/IP is enabled, then the client will use UDP port 137,
TCP port 139, and TCP port 445 (for actual file and print traffic).
