Event ID 1220 — Network Name Resource Availability

  • Article

Applies To: Windows Server 2008

In a cluster, a Network Name resource can be important because other resources depend on it. A Network Name resource can come online only if it is configured correctly, and is supported correctly by available networks and network configurations.

Event Details

Product: Windows Operating System
ID: 1220
Source: Microsoft-Windows-FailoverClustering
Version: 6.0
Symbolic Name: RES_NETNAME_ONLINE_RENAME_RECOVERY_FAILED
Message: The computer account for resource '%1' failed to be renamed from %2 to %3 using Domain Controller %4. The associated error code is stored in the data section.

The computer account for this resource was in the process of being renamed and did not complete. This was detected during the online process for this resource. In order to recover, the computer account must be renamed to the current value of the Name property, i.e., the name presented on the network.

The Domain Controller where the renamed was attempted might not be available; if this is the case, wait for the Domain Controller to be available again. The Domain Controller could be denying access to the account; after resolving access, try to bring the name online again.

If this is not possible, disable and re-enable Kerberos Authentication and an attempt will be made to find the computer account on a different DC. You eed to change the Name property to %2 in order to use the existing CComputer account.

Resolve

Check status of domain controllers

Diagnose and correct connectivity problems with one or more writeable domain controllers. Confirm that the networks in the node are enabled, one or more writeable domain controllers are available on the network, and that elements of the network such as hubs, switches, or bridges appear to be functioning.

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.

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:

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.

Verifying that a Network Name resource can come online

To verify that a Network Name resource 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. In the console tree, click a clustered service or application.
  5. In the center pane, view the status of the Network Name resource you want to verify.
  6. If a Network Name resource is offline, to bring it online, in the center pane, right-click the resource and then click Bring this resource online.

To perform a quick check on the status of a resource, you can run the following command.

Using a command to check the status of a resource in a failover cluster

To use a command to check the status of a resource in a failover cluster:

  1. On a node in the cluster, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. Type:

    CLUSTER RESOURCE ResourceName /STATUS

    If you run the preceding command without specifying a resource name, status is displayed for all resources in the cluster.
