Server 2003 R2 to Server 2008 R2 Migration Problem/Question

I'm having a problem when trying to migrate a Windows Server 2003 R2 Standard Edition to Windows Server Standard 2008 R2.

I've been using this Experts Exchange article as a guide.
Here

I know it's for SBS 2003 to Exchange 2008 and Exchange 2010, but I have used it for other scenarios with success.

Here's where I am currently.

I have performed the adprep on the old server and promoted the new server to a DC and GC.

The old server is 192.168.1.1 and the new server is 192.168.1.3.

I haven't transferred the FSMO Roles yet.  

My thought was that the point of having two DC's in a domain is so that if one is down, the other allows end users to still log in.  So I tried shutting down the old server temporarily and pointing the DNS of an XP Client to the new IP of 192.168.1.3 and it takes a long time to log in.

Also with the 2003 Server shut down I get errors in AD Users and Computers that say the domain doesn't exist and won't let me view anything or even "change domain controllers".

I have the new server's DNS pointing to itself on 192.168.1.3 and the old server point to the new server as well.  Is that correct, or is there something else I missed?

Could I have made the new server a read only DC by accident, and if so can that be changed or should I dcpromo it and demote it and then promote it back up again?

I am an IT Consultant who has many different servers and have done this procedure many times before and never had this problem.  However the old server was setup/installed by a previous company.

Any help would be greatly appreciated.

Thanks!

Has replication completed correctly? Can you run a dcdiag on both servers and check for any errors.
