I'm working on a migration NT4 Server Domain Controller to 2003 Active Directory DC, first step is to install a Secondary DC running Windows Server 2003 on a brand new computer.
I joined this machine to the domain, logged in with an account who is an Domain Administrator, and now I'm trying to dcpromo as a Secondary DC.
On the next screen I'm asking to put informations (username, password and domain) I get an error saying something like "No Active Directory DC named domdom.lan (my test domain) can be reached".
I successfully created a NT4 BDC, I can add rights to other users and navigate/search into them, I can tracert and ping the PDC without any troubles… I don't understand why it doesn't work, so please help me. 🙂
