[Samba] RPC server not available when windows client attempts to join samba AD

[Paul Upson]

Hi Marc,

below are the log files. I cleared the logs and then did the following,
restarted samba with the command service sernet-samba-ad restart, smbclient
-L wmaa2.lan -Upmupson, smbclient //wmaa2.lan/netlogon -Upmupson -c 'ls',
and then I attempt to have a client to join the domain.
