I reply to myself to add some information: I have think that I have traced it down to a name resolving issue. I don't know why but sometimes the client asks the wrong WINS server (I have two: one on the locally connected LAN an another one on the other side of the VPN) to resolve the server's name, and the request fails, then the client cannot connect to the server until it retries the request to the right wins server.
I have tried setting an entry in the client's LMHOSTS file, but still sometimes it asks the wrong wins server. Maybe I have found a workaround: if I use the IP address of the server instead of the netbios name, the client never disconnects from the server, even if idle. Now the question is: why if I use the netbios name, the client disconnects from the server after about 8 minutes idle, and if I use the IP address it never disconnects? Maybe this is a win2000 issue (as a client) more than a Samba issue... -- Fabio "Kurgan" Muzzi -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
