    Windows 2W3 dcpromo in W2K Domain


    by philldmc ·

    I have a stand alone ISA Server running Windows 2003 Server and ISA 2000, named Proxy. This server is NOT a domain controller; it is acting as a stand alone server that is part of our domain. The domain controller is a Windows 2000 based system.

    I want to set up a VPN and from what I?ve read in my setup it would be best to have run on the ISA server. I started the process of installing AD on the ISA machine. I ran the adpreps (Forest and Domain) to prepare the Windows 2000 server. All went fine.

    However every time I try to dcpromo the 2003 server I get this error:

    ?The operation failed because:

    The promotion failed because the name of local computer is the name of a predefined security identifier. Please rename the computer.

    “The requested name already exists as a unique identifier.”?

    I went through the AD and DNS and removed anything relating to ?Proxy? name of the Windows 2003 machine. I removed the Proxy from the domain and I still get this error when trying to dcpromo.

    All my clients are programmed to communicate with ?Proxy? to access the web. How to I promote ?Proxy? to a DC without having to change the name?

      I’m going to answer your question by making you start over from the beginning. Why are you promoting the Win2K3 machine to a DC in order to use it as a VPN server? You do not have to do this. You can use the Win2K3 machine as a VPN server without it’s being a DC as long as it is a member server on the domain. As a matter of fact, it is probably better if your VPN server is NOT a DC, for security reasons. All you have to do is install RRAS on it and configure the RAS server properly.

      Hope this helps!
