[Samba] Why does the server want to connect to a client

[Marc Muehlfeld]

Hi,

I have 5 of 140 Windows XP SP2/SP3 machines that make problems when printing. 
The client open the printer dialog and it takes a long time (up to 1 minute) 
before it appears. Printing is slow, too. Meanwhile I see the following 
messages (repeating several times) in the client log:

[2008/11/21 08:17:28, 1] lib/util_sock.c:open_socket_out(888)
   timeout connecting to 10.1.0.253:445
[2008/11/21 08:17:37, 1] lib/util_sock.c:open_socket_out(888)
   timeout connecting to 10.1.0.253:139
[2008/11/21 08:17:37, 1] libsmb/cliconnect.c:cli_connect(1505)
   Error connecting to 10.1.0.253 (Operation already in progress)
[2008/11/21 08:17:37, 1] libsmb/cliconnect.c:cli_start_connection(1568)
   cli_start_connection: failed to connect to IT-09<20> (10.1.0.253). Error 
NT_STATUS_ACCESS_DENIED

Why does the server tries to open a connection to these clients? On one of the 
5 PCs if I disable the XP firewall, the problem disappers. The log entries 
above are from a client with enabled XP firewall (unchanged standard 
settings), but there are no changes when I disable it. Some of problem clients 
only show the "timeout connection to..." messages.

I used samba 3.0.22 until yesterday, but the problem still exist after 
upgrading to 3.0.32.

Any suggestions?
