I have a customer with an existing Active Directory domain/forest with multiple DCs. All servers are Win2K3. DNS is installed only on DC1 at the current time. DC2 and DC3 do not currently have DNS. I want to install DNS on DC3 and have DNS be active directory integrated. However, whenever I add DNS to DC3, it refuses to create the forward lookup zones and the those zones don't replicate to DC3. However, the reverse lookup zones DO automatically appear (replicate) immediately after installation. More info: DC1 was originally an SBS server on which the customer (themselves!) used the Microsoft Transition Pack to "upgrade" to the mainline MS products. The customer himself promoted DC3 to be a DC but did not elect to add DNS at installation time. DC3 will be moving to support a branch location and so it will need to have DNS on it.
