[dba-Tech] Restart network services on a server

Hi All:

I am at a client's site and running a full rebuild of their database server and then became aware that no one on the network can connect in. 

It appears that the networking service has to be restarted but the server can not be rebooted until the database is rebuilt. I have run the basic "net stop and start" but it doesn't work. 

Would anyone know off hand what service(s) that would need restarting?
