I've run dcpromo on a new member server for a new branch office.
I successfully joined the domain, set iit to a fixed IP and installed DNS. dcpromo seems to work, but the DNS Forward Lookup Zones dont get filled in.
I can see that the system has put the Server into the right SItes & services site and it's been put in the Domain COntrollers OU in AD users and Computers. I can ping the main office server and vis-versa.
Looking at the DNS Event Logs, I can see an Event IF:800 notice saying
===The zone <subnet>.in-addr.arpa is configured to accept updates but the A record for the primary server in the zone's SOA record is not available on this DNS server. This may indicate a configuration problem. If the address of the primary server for the zone cannot be resolved DNS clients will be unable to locate a server to accept updates for this zone. This will cause DNS clients to be unable to perform DNS updates.====
Looking at the DNS console, there is no forward lookup zone but one reverse lookup zone for the main sites subnet. I also get a NTFrs error 13508
=The File Replication Service is having trouble enabling replication from \\MainOfficeServer.mydomain.local to BranchServer for c:\windows\sysvol\domain using the DNS name \\MainOfficeServer.mydomain.local . FRS will keep retrying.
Following are some of the reasons you would see this warning.
1] FRS can not correctly resolve the DNS name \\MainOfficeServer.mydomain.local from this computer.
 FRS is not running on \\MainOfficeServer.mydomain.local
 The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers. . =
I'd really appreciate help in fixing this.
