The DC may be using incorrect DNS servers, or there may be a problem with the records registered in DNS. To verify that the DC is using the correct DNS servers, open an elevated command prompt and run the ipconfig /all command. Locate the DNS servers listed for the DC's network adapter: A http://www.dell.com/support/article/us/en/04/SLN266126/en domain controller, like any machine in a domain, should use only DNS servers that are internal to the domain; the only place external DNS servers should appear is in the list of forwarders configured on an internal DNS server, if forwarders are being used. Please see Best Practices for DNS Configuration in an Active Directory Domain for further information on configuring DNS. If the DC's DNS servers are incorrect, they should be changed in the properties of the server's network adapter, as shown below: After correcting the DNS servers, run the following four commands from an elevated command prompt: ipconfig /flushdns ipconfig /registerdns net stop netlogon net start netlogon These commands will ensure that the DC has no incorrect DNS data stored in its resolver cache and that all of its resource records will be properly registered in DNS so that other domain-joined machines can locate it.
