Force deletion of root?  Namespace server {0} is not online. Do you want to forcibly remove the namespace server and delete the namespace? You might have difficulty creating new namespaces on {0} in the future. If so, use Dfsutil.exe to remove this namespace on {0} when it is back online.  If {0} has been decommissioned, you can safely force this operation.
