DFS root could not show in MMC and root target could not be removed

I have 2 problems. There are 3 domain DFS roots, namely, dfsris, dfsdpt and
dfsrpt. The first 2 can be shown in DFS mmc, but when I attempts to show the
dfsrpt, it gave "the specified domain does not exist or could not be
contacted".
The 2nd problem is in the 'dfsdpt' dfs root, there is one root target hosted
by a DC which was forcefully demoted. When I tried to remove the target, it
gave "The indicated server share does not support the indicated DFS
namespace" and then asked "Do you want to forcibly remove the DFS root?". I
clicked 'Yes', it then gave an error "The system cannot find the file
specified". The root target remains.

I have tried the technet itsolutions,
http://www.microsoft.com/technet/itsolutions/cits/mo/winsrvmg/fspog/fspog5.mspx,
problem #6 but there isn't any registry key called DfsDnsConfig (as
indicated in the article) on those servers.

 

Basically this happens when the root referred is no longer available or
doesn't know about the root. You should be able to delete the root from DC.
You have the root in the DC - Delete the root which you want to get rid from
the DC. If you don't have it in DC, then remove the root from DFS registry
key.

After removing from DC and machine, restart the dfs service and root would
not show up anywhere.

 

Hii Sing Chung,

Just an added information, this article tells you how to do a Force Deletion
of the DFS root.
