  • Proper method to replace AD master

    I have tried this once, and did not have success.
    I have an existing AD with one domain server. The domain server is windows 2000 server. I purchased a new server to replace it. The new server has windows 2003 R2 server on it. Here is what I have done:
    1. On the windows 2000 server, I ran the addprep for forest and domain.
    2. On the windows 2003 server, I ran dcpromo. It completed successfully, and rebooted the server.
    3. Setup DNS server on the 2003 server.

    I tried moving the roles from the 2000 server to the 2003 server. It worked with no errors, but when I powered down the 2000 server, the domain became laggy logging in, managing, etc. Also, on the 2003 server it gave errors about contacting the domain server. I tried running dcpromo on the windows 2000 server so I could remove it from the domain, but generated an error about contacting the domain controller. So, I transferred the roles back to the 2000 server.

    What are the proper steps so I can finish this replacement ?
    How can I verify that I have the dns server on the 2003 server setup right ? It resolves domain names, and I can access websites, etc.

    thanks for any help,

    Did you make the new Domain Controller a Global Catalogue??

    It does not do this by default when promoting a DC, it only does this for the very first DC in a new domain.

    Let me know how you get on.

    I would run DCDIAG and NETDIAG on the new DC to see if there are any issues

      Yes, in my first attempt (failed) I made the new windows 2003 server the global catalog (checked the box). I cleared the checkbox on the windows 2000 server to deactivate it as a global catalog.
