Cluster network name resource failed a health check

Check for hardware or software errors related to the network adapter. Also, you can run the Validate a Configuration wizard as described in "Using the Validate a Configuration Wizard to check the network configuration of the cluster."

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 this procedure, you must be a member of the local Administrators group on each clustered server.

Using the Validate a Configuration Wizard to check the network configuration of the cluster

To use the Validate a Configuration Wizard to check the network configuration of the cluster:

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, in the console tree, make sure Failover Cluster Management is selected. Then under Management, click Validate a Configuration.
3. Follow the instructions in the wizard to specify the cluster you want to test.
4. On the Testing Options page, select Run only tests I select.
5. On the Test Selection page, clear the check boxes for System Configuration and Storage. This leaves only the tests for Network and Inventory. You can run all these tests, or you can select only the specific tests that appear relevant to your situation.
6. Follow the instructions in the wizard to run the tests.
7. On the Summary page, click View Report.

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:
   • Search System Error Codes ( http://go.microsoft.com/fwlink/?LinkId=83027).
   • Click Start, point to All Programs, click Accessories, click Command Prompt, and then type:
