I had a dead PDC and another not so synced domain controller for my domain. using comments here link now the so called secondary domain controller has seized domain controls and I can verify it from dsa.msc that it is a domain controller.
I set up another domain controller (win2003SRV) and about to promote an AD on it as a domain controller for my domain. When I try to join the new domain controller to the domain I face DNS problem. here is some more detail
DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain DOMNAME.A.B:
The query was for the SRV record for _ldap._tcp.dc._msdcs.DOMNAME.A.B
The following domain controllers were identified by the query:
Common causes of this error include:
- Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses.
- Domain controllers registered in DNS are not connected to the network or are not running.

it is worth noting that update.DOMNAME.A.B is the current domain controller to which I'd like to add another controller named PDC.DOMNAME.A.B
Ip address of update.DOMNAME.A.B is 192.168.200.1 and for pdc.DOMNAME.A.B is 192.168.200.100
querying DNS on both machine return correct results.
