DC promotion

I want to make sure that a "typical" DC promotion should work in my domain. I have 1 domain with two sites connected by an MPLS network. I want to promote a member server running 2003 to a DC in Site 2. In site 2 I have a dc running on a windows 2000 server. It is the only 2000 server left at either site. After promoting the 2003 server I would like to demote and remove the 2000 server from Site 2. I have two domain controllers at site 1, both running windows 2003. The global Catalog server is at Site 1. The windows 2000 server that I will be demoting  is running my DNS and DHCP. Is there any thing special I should know in order to successfully promote the 2003 server and demote and remove the 2000 server at site 2. If I cam follow some standard procedures for the promotion and demotion, then I should be fine. This is the first one I have done on my own.  The windows 2000 server is running my DNS and DHCP

DNS is AD integrated so the new 2003 server will have that once promoted (assuming DNS service is installed).  

Follow this to migrate DHCP:


Once you change your DNS for clients to point to the 2003 server, I would suggest stopping DHCP and DNS services on the 2000 server and allow a few days to pass.  If clients are working fine, then go ahead and demote it.  Would suggest making the 2003 server a global catalog for that site.  Also make sure AD intersite replication is working with the 2003 server before removing the 2000 server.

You should just promote the 2003 server to a domain controller by running dcpromo allow DNS to be create and installed during dcpromo wizard. Once the server has been promoted wait for a bit run dcdiag to check for any errors. If all clean you can proceed to make this server a global catalog.

If you want to move DHCP here is a link on that http://support.microsoft.com/kb/325473

On Windows 2000 server you can proceed with demotion once there aren't any errors in dcdiag from 2003 server. To demote you run dcpromo this will demote the server as well.

Very similar question over at the TechNet forums that I'm currently helping with


I'd personally make all these boxes global catalog.  Do you plan on moving DHCP, that can be done too, more on that here:  http://support.microsoft.com/kb/325473

Thanks. If and when I demote the 2000 server, do I need to do any clean up in AD? Sites and services etc.? Or will any replication taking place clean up on it's own with the demotion?
Darius GhassemCommented:
With demotion if the system is running properly all will be remove during demotion then replication will replicate to other Domain Controllers about the demotion
Mike KlineCommented:
You will have to delete it from sites and services...that is one thing that doesn't happen automatically.
