DFS-N: Namespace Initialization

Microsoft.Windows.FileServer.DFSN.6.3.RootTarget.ErrorOnRoot (UnitMonitor)

This object monitors the initialization of namespace roots and creates an alert if a namespace root doesn�t initialize properly.

Knowledge Base article:

Summary

This object monitors the initialization of namespace roots by looking for the presence of DfsSvc event 14534 in the System event log. If this object detects the event, it sets the health state of the monitor to Critical, indicating that the namespace is offline and triggers an alert.

Causes

If the namespace is a domain-based namespace, it could fail to initialize for the following reasons:

Network connectivity problems are preventing the namespace server from reaching a domain controller.
Changes were made to the DFS namespace directly in Active Directory Domain Services (AD�DS) instead of using DFS Management or command-line tools.

If the namespace is a stand-alone namespace, it could fail to initialize if the DFS Namespace service cannot locate the metadata for the namespace in the registry of the server. This can occur because of registry corruption.

Resolutions

Restart the DFS Namespaces service

To restart the service, use the Services snap-in, the Windows PowerShell Start-Service and Stop-Service cmdlets, or command-line tools such as net stop and net start. To restart the service remotely by using the sc command, open a command prompt window and then do the following:

1.To stop the service, type the following command, where [servername] is the Universal Naming Convention (UNC) path to the remote server:

sc [servername] stop dfs

2.To confirm that the service is in the STOPPED state, type the following command:

sc [servername] query dfs

3.To restart the service, type the following command:

sc [servername] start dfs

Note: To restart a service, you must be a member of the local Administrators group on the affected server.

If restarting the service does not resolve the issue, the namespace server might not be able to contact a domain controller.

Test communication with AD�DS

To test communication with AD�DS, use the dfsdiag /testdcs command. Confirm that all domain controllers report healthy results.

Verification

To verify that this issue is no longer present, use the following procedure:

1. Open a command prompt window and then use the dfsutil root\\[namespace] command (on Windows Server�2003, use the dfsutil root\\[namespace]/view command) to check the state of the namespace.

2. Confirm that the state of the root is OK and that the states of all namespace servers are Online.
