DFS - The namespace cannot be queried The RPC server is unavailable

 

 

Check the registry item under:

HKLM\Software\Microsoft\Dfs\Roots\Domain Key

See if it's listed there, if it is and your certain nobody uses is, you can delete it.

Also within ADSI Edit on your DC you could have that item listed.

Look under:

DOMAIN > DC > CN=System > CN=Dfs-Configuration

See if it's listed there, if it is and your certain nobody uses is, you can delete it.

 

After that perform the following commands:

dfsutil cache provider flush
dfsutil cache domain flush
dfsutil cache referral flush
dfsutil /pktflush
dfsutil /spcflush
dfsutil /purgemupcache

Wait for about 1 minute to start up the DFS Management Console and recreate the DFS Share as you initially wanted.
