This monitor enters the Critical condition if the specified namespace root has been disabled by a namespace administrator.
Enable the namespace
Open an elevated command prompt on a computer running Windows Server 2008 R2 or Windows Server 2008 and then use the Dfsutil Property State Online \\<namespace> command.
Note: To enable a DFS folder, you must be a member of the Local Administrators group on each namespace server.
To verify that this issue is no longer present, use the dfsutil root\\<namespace> command (on Windows Server 2003, use the dfsutil root\\<namespace>/view command) to check the state of the namespace. Confirm that the state of the root is OK and that the states of all namespace servers are Online.
After you resolve the problem, in the Operations console, reset the health state of this monitor to Healthy.
