Hello,

I'm currently added another windows 2003 Dc  to my small environment. I brought the new 2003 server onto my network and preformed a dcpromo. I'm also looking to make it a back dns server. After I Dcpromo'd the server i also installed DNS server on it, And now when i go into the DNS portion of the server i see all my current dns info from my network. Does this mean it's already a back dns or am i missing something. It just seems too easy.

Let me know?

No that's it. With Active Directory Integrated DNS, DNS is replicated to all domain controllers.
You might want to configure your clients so that they are set to use one machine as their Preferred DNS server and the other as the Alternate DNS server, that way id one DNS server fails they will query the other.

It would also be quite a good idea to make both machines a global catalog server,  its just a tick box in Active Directory Properties.

Another question , with the global catalog server. In a Single Domain environment with one dc , when people are logging into the network , their account must contact the gc in order to logon?unless it's already cached, correct?

And also in the one domain environment, if i have the the first dc with the gc and since im adding the secondary dc . if i did not want to enable gc on that server when people are authenticating towards that server it should forward the gc requests to the main server?

i've been try to read around and i was just hoping for some clarity. hopefully i have made sense.
