DFS: the namespace server cannot be added the specified domain either does not exist

We recently setup DFS on two 2008 servers in a windows 2003 AD environment.  We had some configuration woes with the first testing and decided to start over with the process.  We are now getting the error:  "the namespace server cannot be added the specified domain either does not exist" when attempting to create the new namespace in the namespace wizard.

I have manually removed DFS information from the domain controller according to: " Manually remove DFS

I have also checked for registry entries on all servers involved.  Completely removed DFS from the two 2008 servers.  Re-installed DFS on both.  Restarted DFS services on all servers involved including secondary domain controller.  Forced replication after making changes with AdsiEdit.

When running nslookup domain.com I get:

Server:  jupiter.domain.com

Name:    domain.com

The server is the Mercury.domain.com server and it is the PDC.

Please advise on how I can move forward and let me know what additional information I need to provide.  Goal is to replicate data between the two 2008 servers.

Thank you

I would like to add that I am also getting errors when trying to Delegate Management Permissions to domain.com.  It gives the same "domain does not exist or can't be contacted."  Almost seems like a dns issue.

I have gone through the steps listed in the KB.  I deleted the dfs remnants in the ADDS with the Adsiedit.msc tool.  I also checked for registry keys and restarted the services on all servers involved.  Still getting the same issue.  

Something odd is that testing the Delegate management Permissions works for our two other domains but does not work for our primary domain.  Currently we have 3 domains on the network for different locations in the state:


If I choose to Delegate a permission to domain-gc.com it has no issues.  

I should also state that this all worked the first few times we ran tests on setting up dfs.  It wasn't until the namespace was deleted that the current problem started.

I was able to resolve the problem by starting the Net Logon service on the PDC.  I am not sure why this service was stopped, it was set to automatic.  

I found the following error in the event viewer on the domain controller:

"attempt to determine whether user and machine accounts are in the same forest failed"

After searching that error, I was able to find the recommendation to make sure the Net Logon Service was started on the DC.

I was able to create my Namespace successfully.
