I've just promoted a W2K Adv. Server that is a router between a DMZ and a private zone (DMZ is internet routable, private is 192.168.X.X) to a Domain Controller without installing a DNS Service on that server since I have one in the DMZ. The domain controller now claims that there is no DNS available for the domain which results in Netlogon problems and DHCP - dynamic DNS update problems. This despite the fact that the newly created DC has DNS records on the DMZ interface and the DHCP server also publishes these NS records to the DHCP Clients.
Do I have to install a DNS on the Domain Controller and delegate a zone for this so that the DC is happy?
