Summary

This object monitors the ability of the namespace server to communicate with Active Directory Domain Services (AD DS) by looking for the presence of DfsSvc event 14526.

Causes

The DFS Namespace service failed to contact a domain controller. This can occur for many reasons including:

  • Network connectivity issues

  • No domain controllers are currently available

Resolutions

To test network connectivity with the affected server, use the following procedure:

1. Open a command prompt window and then use the ping command to check basic network connectivity. If the ping command fails, it is likely that the server is not running, or has network problems that require local access to resolve. If Ping is blocked in your network environment, skip this step.

2. If the ping command is successful, test the server’s registration in DNS by using the nslookup command. If the nslookup command fails, there is a problem with DNS. Check the DNS server health or contact the DNS server administrator.

3. If the nslookup command succeeds, it is likely that the shared folder is offline (possibly for maintenance) or there are problems with the permissions on the shared folder.

If communication with a domain controller fails, or DFS metadata is inconsistent, restart the DFS Namespace service (Distributed File System on Windows Server 2003).

To do so, open a command prompt window on the affected server and then type the following commands:

net stop dfs

net start dfs

If restarting the service doesn’t resolve the issue, you might need to restart the affected domain controller.

After detecting DfsSvc event 14529, this monitor resets to a Healthy state.
