Hey Everyone.  
Heres the quick scenerio I ran into, and need some steps to take.
I have installed 2 2003 SP2 servers on VMware GSX, sitting on a Fresh install of Windows XP PRO.
I ran DCPROMO on Server 1 (Test-DC, 192.168.0.10), and created the testIT.test (during DNS portion of the setup).
On second server (Test-DC2 192.168.0.11) I ran DCPROMO and chose adding an addtional server to the domain.  It found the domain fine.
I was able to create users on DC and they replicated to DC2 fine.
I was able to RDP using NetBios names on another XP unit, when it was still part of a WorkGroup. SInce I added this XP unit to the domain, I cannot RDP using Netbios names to either server, unless I use IP.
- In the DNS portion of each server, I have added each others IP for DNS .

I am unable to use NetBios name to  RDP to either server, from DC toDC2 or vice versa.

I would say that since you joined the domain, the XP system is automatically appending a domain to the names for resolution.    

So instead of just searching for server1, its searching for server1.domain.com (or something like that)

ALso check that DNS is  OK and run DCDIAG as well as Netdiag on the servers.


I hope this helps !

Make sure your servers don't have 127.0.0.1 in their TCP\IP settings for DNS. List only internal DNS servers in their TCP\IP properties. The samething for the clients.

Sorry so your DNS servers listed in the TCP\IP properties for clients and servers should be 192.168.0.11 & 192.168.0.10

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Thanks to all who have helped soo far.

Just to be clear, these 2 servers are fresh installs.  I added DNS during DCPROMO, so I havent performed any configurations to DNS.  Further more, When I shutdown DC1, I would think that the backup DC2 should run the show...This didnt happen.

I will test your answers, and hopefully someone is online to help when Im in front of the testbed.

When you Dcpromo the DNS settings go to 127.0.0.1 which need to be the IP address of your server. The backup DC2 needs to be a Global Catalog to take logon requests.

HMM, I wonder if the XP box took over as domain master browser.

Can you look at the PDCe and see if you have 8021 or 8032 errors in event logs?

Since I added DNS of each DC to one another i.e. DC1 has DNS IP's of Both servers.  It is workign correctly.
