Samba : 2.2.7a compiled with gcc 2.95.3
clients : about 100-200, worldwide (mix of W2K and XP)

showed by "netstat -an" grows for connections inactive for many hours
(long client night jobs finish during night, then inactive until user
comes back at morning).
The password server is a Windows box (W2K), role = PDC.
We initially suspected a firewall between the samba server and the
password server, which would drop inactive TCP sessions. The net guy says
there is no such FW between the boxes.
Any idea what would be the cause of these staled connections, and how to
