RE: [ActiveDir] _Msdcs.domain.com Zone Creation

[Santhosh Sivarajan]

Simple answer: It is by design.  In windows 2003, if you have a DNS zone, the DCPROMO process won’t create a _msdcs.domain.com.  You have to manually create it.  To create a _msdcs.domain.com after the DCPROMO, create a new forward lookup zone called _msdcs.domain.com and restart the Netlogon service.  It will automatically move all the _msdcs subzone to newly created _msdcs.domain.com zone.  And the _msdcs subzone will become a delegated zone. My recommendation: Create a DNS zone first and make sure everything ok before do the DCPROMO.  I don’t like the fancy DCPOMO+DNS method.

Server points to itself as primary DNS server and registered itself in the domain.gov zone. I then ran dcpromo. Dcpromo saw that DNS was already configured and continued with the install. After reboot, the _msdcs, _sites, _tcp, and _udp zones were created under the domain.gov zone. The forward lookup zone _Msdcs.domain.gov zone was not created. Dcpromo without DNS configured first: Server points to itself as primary DNS. DNS in not configured. I ran dcpromo. Dcpromo saw that DNS was not already configured and offered to install it for me which I chose to do. I set up domain.gov and continued with the install. After reboot, the _msdcs, _sites, _tcp, and _udp zones were created under the domain.gov zone. The forward lookup zone _Msdcs.domain.gov zone was also created. Why does the _Msdcs.domain.gov zone not install when dcpromo is run with DNS already configured. How can I create the _Msdcs.domain.gov zone.   what is the best method for configuring DNS on first DC in forest root domain? configure DNS, then run dcpromo? or let the dcpromo process configure DNS?   Thank you Nathan
