I'n my case if one protocol (TCP or UDP) in that port is enabled things 
seem to work. if both are disabled i get the error message. Have you 
tried to disable firewall on samba4 host just to rule it out? Presumably 
you don't have any other firewalls in the way? I will try to join 
Windows 2008 to the domain tomorrow as a test.
