Windows 2003 Domain Controller

Posted on 2011-10-21

I started to work for a company. They have 2 Windows 2003 Domains, lets call them Domain1 and Domain2, and each domain has 1 Domain Controller.
Is it possible to have the DC for Domain1 act as a DC for Domain 2 and vice versa? If so how do I set that up?
The IT guy here says thats the way things are setup.
I assumed DC's can only act as DC's for the domain they belong to. Am I wrong?

    DC's can only be members of a single domain - perhaps a virtualization technology would allow more efficient use of your hardware for multiple server roles...

    NO. You have to have a trust relationship between the two domains.

    Perhaps you should examine why they have two separate domains? With Windows 2003, you can merge the two domains and then each controller will backup the other. Proper permissions and controls would let you have one domain and still keep users separated.

    Go into the Domains and Trusts snap-in.  That will shed some light on whether the two domains are set up as a trust.

    Domain Controllers are specific to 1 domain only.

    Will setting up the trust between the 2 domains, allow the DC from DomainA act as a DC for DomainB and vice versa?
    My goal is to have a failover if a DC goes down.

    In that case you have to install the second domain controller on each domain.

    No redundancy through the trust, just eases communication between domains
