remove 2008 DFS Namespace Server

I have 3 2003R2 DFS Namespace servers that replicate our DFS Structure.  I added a 2008 Domain controller and made it a dfs namespace server.  We have been experiecing extreme delays when dfs root from 2003r2 terminal server clients, especially when you right click a file and click properties (2-3 minutes).  We do not have any "Folder" replication currentl in place, only the dfs folder structure and links replicates between all of the dfs namespace servers.

I think I want to remove the 2008 server as a dfs namespace server (basically I do not want clients getting our dfs mappings from the 2008 server)  how do i stop the replication of the dfs structure on the 2008 server and remove it as a namespace server.

I read several articles that say you should force your namespace servers to use DNS by adding a registry entry. to hklm\system\currentcontrolset\services\dfs\DfsDnsConfig set to 1 (which I had done on my 2003r2 servers years back and all of my links in dfs are using IP addresses \\10.90.1.7\sharename$) is there something I need to do to the 2008 server to force it to use DNS especially since there are no 2008 wins servers?

Thank you in advance.

YOu might concider just migrating the DFS root over to 2008 as well. I dont think 2008 is as much the culprit , as they may not play togethr well. - I would get familiar with manipulating the DFS structures. you can do anything you want. Its up to you and how you want to move forward:

I thought this one looked pretty good too:

I figured out how to remove the dns namespace from 2008.  actually i removed it from all servers but one 2003r2 domain controller.  after 30 minutes all navigations through dfs root went back to normal.  I believe it has more to do with having 2003r2 servers accessing a 2008 domain controller and problems with SMB2 (which i have disabled on the 2008r2 domain controller).

we still are seeing delays in our ERP software (which uses dfs to get ini settings), i am ready to transfer all of the roles back to 2003r2 and bring down the new 2008 domain controller... it's been a long 3 weeks.

I moved all the roles back to 2003r2 domain controller, pointed all computers back to 2003r2 domain controller, shut down network and brought it back up.  all is back to normal.  2003R2 to 2008 Domain controller with dfs  pointing to 2008r2 file server just does not work.
