Hi
I configured my SME gateway server to act as Domain controller from Server-Manager which successfully saved new setting but after that for testing when i am trying to join  windows client with DC but its refuse with error that 
"A domain controller for the Domain "LR5" could not be contacted "  
 "Ensure the domain name is typed correctly."
Please let me know which name of server will the domain name as i tried all names
Server name:        Lh5
Domain name:       test1.local
full name:             Lh5.test1.local
work-group name:  test1
but none of them work, please note from same machine server manager is accessible so problem is not related with IP or class setting etc.
