In DFS Management, when we try to manage one of the namespaces, the error is:

\\mydomain.com\mynamespace: The namespace cannot be queried. The specified domain either does not exist or could not be contacted.

When I use dfsdiag /testdfsintegrity /dfsroot:\\mydomain.com\mynamespace, the output is:

Error: The RPC server is unavailable.
Error: The specified domain either does not exist or could not be contacted.
Warning: Unable to access the DFS metadata for the following namespace: \\myserver\mynamespace
Finished TestDfsIntegrity.

We retired myserver within the last few months. I speculate that it was the only namespace server for this namespace. I can still browse this namespace in file explorer; I just can't manage it in DFS Management.

Is there a way to set up another server to be the namespace server for this namespace?

My solution was to delete the namespace and recreate it.

Before deleting it, I needed to record what folders were in the namespace. Fortunately, I could still browse the namespace in file explorer. I made notes about what everything was pointing to.

I could not use the DFS Management tool to manage the namespace at all. To delete it, I did the following:

  1. Run adsiedit.msc.
  2. Connect to the default naming context.
  3. Navigate to DC=mydomain, DC=com > CN=System > CN=Dfs-Configuration.
  4. There is listed all of the namespaces. Delete the problem one.
  5. Running the commands "repadmin /syncall" and "dfsrdiag pollad" supposedly cause everything to sync up.
  6. Then I could use DFS Management to recreate the namespace.
