Resolve

Check DFS namespace configuration

Check the DFS namespace configuration by opening the DFS Management snap-in as described in "Opening DFS Management within Failover Clustering Management."

If you do not currently have Event Viewer open, see "Opening Event Viewer and viewing events related to failover clustering." If the event contains an error code that you have not yet looked up, see "Finding more information about error codes that some event messages contain."

To perform the following procedures, you must be a member of the local Administrators group on each clustered server, and the account you use must be a domain account, or you must have been delegated the equivalent authority.

Opening DFS Management within Failover Clustering Management

To open DFS Management within Failover Clustering Management:

  1. To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the Failover Cluster Management snap-in, if the cluster you want to manage is not displayed, in the console tree, right-click Failover Cluster Management, click Manage a Cluster, and then select or specify the cluster that you want.
  3. If the console tree is collapsed, expand the tree under the cluster you want to manage.
  4. Expand Services and Applications and then click the clustered DFS namespace instance.
  5. In the Action pane, click Manage DFS and then use the DFS Management snap-in to view and configure the namespace.

    Note that if this is the first time you have configured this clustered DFS namespace in DFS Management, you will need add the namespace to the DFS Management display.

Opening Event Viewer and viewing events related to failover clustering

To open Event Viewer and view events related to failover clustering:

  1. If Server Manager is not already open, click Start, click Administrative Tools, and then click Server Manager. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the console tree, expand Diagnostics, expand Event Viewer, expand Windows Logs, and then click System.
  3. To filter the events so that only events with a Source of FailoverClustering are shown, in the Actions pane, click Filter Current Log. On the Filter tab, in the Event sources box, select FailoverClustering. Select other options as appropriate, and then click OK.
  4. To sort the displayed events by date and time, in the center pane, click the Date and Time column heading.

Finding more information about the error codes that some event messages contain

To find more information about the error codes that some event messages contain:

  1. View the event, and note the error code.
  2. Look up more information about the error code in one of two ways:

Verify

Verify that the clustered DFS namespace can come online, and observe whether additional events are logged regarding resources in the clustered DFS namespace.

To perform the following procedures, you must be a member of the local Administrators group on each clustered server, and the account you use must be a domain account, or you must have been delegated the equivalent authority.

To verify that a clustered DFS namespace can come online:

  1. To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the Failover Cluster Management snap-in, if the cluster you want to manage is not displayed, in the console tree, right-click Failover Cluster Management, click Manage a Cluster, and then select or specify the cluster that you want.
  3. If the console tree is collapsed, expand the tree under the cluster you want to manage, and then expand Services and Applications.
  4. Click the clustered DFS namespace that you want to view. In the center pane, view the status of the clustered DFS namespace and its associated resources. As needed, expand one or more visible resources until you see all the clustered resources you want to view.
  5. To bring a clustered DFS namespace online, in the console pane, right-click it, and then click Bring this service or application online. You can observe the status of the associated clustered resources as the Cluster service attempts to bring them online.
