Having trouble adding a windows 2008 server r2 into a win 2003 domain; the domain has 3 domain controllers (2 server 2003, 1 server 2008), all three are at win 2003 forest and win 2003 domain functional level.
I joined the new server to the domain as a member server –all is well. When I run the AD services installation wizard on the new server to “dcpromo” it to a domain controller, I get “to install a domain controller into this AD forest, you must first prepare the forest using “adprep/forestprep”. The utility is available…”
So, I go to each existing domain controller and run adprep/forestprep. On each one, I get a favorable return “forest wide information has already been updated”.
Then I run adprep/domainprep on each one. The 2 win2k3 servers tell me the “domain wide information has already been updated”. On the existing 2008 server, the adprep command just returns a prompt, with no indication of anything running.
All three existing Domain controllers host the Global Catalog server.
On the new 2008 server, I ran the AD installation wizard which completes successfully. Then, Dcpromo fails with the error message above.
What are my next steps?
