hi jerry,

thank posting in windows server forum.

after referring error, seems have dns issue in case can’t locate dc. please check setting related dns issue following. (below quoted this thread)

if case, recommend proceeding that:

1. make sure each dc has 1 ip address in use , 1 nic card enabled (other nics should disabled)
2. make sure public dns servers configured dns forwarders , not in ip settings of dcs
3. choose healthy dc / dns server , make each dc point primary dns server
4. make each dc / dns server point private ip address secondary dns server
5. make sure needed ports ad replication opened: http://technet.microsoft.com/en-us/library/bb727063.aspx
6. check dns zones , remove manually obsolete / unused dns records dcs

once done, run ipconfig /registerdns , restart netlogon on each dc have.
on client computer, run ipconfig /flushdns , check again.

hope helps!

thanks.
