First, I am upgrading from an NT 4.0 PDC to Active Directory. I have made a test environment. I first created a new BDC then promoted it to a PDC. I then took it off the network and upgraded it to Win2k server. Of course it asks for a DNS server, which is then installed on the server. It looks like it isn't installed properly -- I do not get the four sub folders (_TCP.domain, etc.). Could it be because I am not connected to the Internet? When I connect it to the test network and modify the other systems on it to register with the DNS, they do -- however, login is very slow.
My next question is along the same lines.
I've tried to upgrade two different ways: taking the PDC off of the network and upgrading, and, leaving it on the network and upgrading it. During the latter scenario, when asked to type in the domain name, I do, and the system says that there is one already there. So I unplug the network cable and type in the domain name, get past that section and connect it back in. Then it cannot find the DNS.
We are using a single name domain i.e., "mydomain" there is no "." or anything else attached to it, and the only difference in the test domain is all internal cannot access the Internet or anything on the production network.
