DNS Issue RRS feed

  • General discussion


  •  I am looking for some help with DNS.  I have created a new domain controller for an existing Windows NT 4.0 domain.  I then promoted that domain controller to PDC and upgraded it to 2003 Server.  Now, in trying to add DNS, I get an error: "this computer is connected to networks with different or invalid namespaces."  My question(s) is/are related to this error.  First, is it possible to use the existing domain name that I discovered is NOT registered with the company - and, it's already taken?  And/Or, if not, how can I get an existing NT 4.0 domain name (using WINS) to "move" to 2003 Server and DNS with a name that I did register (keeping user and computer accounts)?

    Thanks,
    Greg
