An AD DC controller for the domain could not be contacted.

This is error i get when trying to join the domain with a client.  This just started out of nowhere.

  An AD DC controller for the domain could not be contacted.    DNS was successfully queried for the SRV record.  The follow domain controllers were identified by the query

However no Domain Controllers could  be contacted.

I shut firewall down, and it is happening on a win7 client and a win 2008 member server I am trying to join.  I also tried joining a win xp client, same results.  I ran netdiag and dcdiag verbose and looked at logs, and all the tests passed

This is the error:

The query was for the SRV record for _ldap._tcp.dc._msdcs.local

The following domain controllers were identified by the query:
server1.local
data-server.local


However no domain controllers could be contacted.

Common causes of this error include:

- Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses.

- Domain controllers registered in DNS are not connected to the network or are not running.

I found the issue.  It has to do with single label dns domains.  I will work on changing that.  I adopted a domain that was already configured as single label DNS
