Event ID 1051 — Network Name Resource Availability

Applies To: Windows Server 2008 R2

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: 1051
Source: Microsoft-Windows-FailoverClustering
Version: 6.1
Symbolic Name: RES_NETNAME_NO_IP_ADDRESS
Message: Cluster network name resource '%1' cannot be brought online. Ensure that the network adapters for dependent IP address resources have access to at least one DNS server. Alternatively, enable NetBIOS for dependent IP addresses.

Resolve

Confirm name registration

If you do not currently have Event Viewer open, see "Opening Event Viewer and viewing events related to failover clustering." After viewing event messages, review the following settings:

  • Confirm that the Network Name resource is dependent on an IP Address resource. For more information, see "Viewing properties of an IP Address resource or Network Name resource in a cluster."
  • For the IP Address resource that the Network Name resource is dependent on, confirm that the NetBIOS settings (if used) or Domain Name System (DNS) settings match the name resolution services on this network.
  • Check that a DNS server or (if used) a WINS server, or both, are correctly configured and are online.

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.

Viewing properties of an IP Address resource or Network Name resource in a cluster

To view properties of an IP Address resource or Network Name resource in a 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, 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, expand the Name listing (Network Name resource) for the clustered service or application.
  6. Right-click the resource you want to view, and then click Properties.
  7. View the properties of the resource. If you want to also view the dependencies for the resource, click the Dependencies tab.

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.

Verify

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.
