Hello!

I think, what you are seeing is the same that I reported some time ago.

When you open a printer connection to the samba server as 
"printeradmin", the IPC$ connection is closed after a short time by the 
windows client (this is a spoolss pipe).

When you open a printer connection (means: open the printer window or 
print) as "normal" user - the connection is held open forever.

No idea, why this is. But the connection is definitly not closed by the 
client.

If this is a problem on your system (as is on mine), you might have to 
close this remaining connection manually.

I do this in conn.c / conn_idle_all(). But there might really be more 
elegant ways...


Bye,
