Problem with two NICs in the server


I’ve installed UrBackup server in a 2008 Server with two NICs, and, the clients in works ok, but the clients in does not works, I can see the PCs with ping, view shared folder and any other tasks, but the only UrBackup client in that side of the lan (Win7) does not reach the server. I’ve disable both firewalls but the issue still is there.

How can I check the conectivity between clients and server? Also, the server does not perform a cleanup, is there any way to force it?


Update: if I restart the Urbackup service (server), the lost client appears in the client list inmediatly :o
