CAUSE:

This is caused by the script querying for a machines DNS name from the MT_Computer table when the table is not populated correctly.

RESOLUTION:

To work around this issue do the following:

1. Get a list of machines that are missing the DNSName attribute.  In SQL Query Analyzer run:

     select NetbiosComputerName,DNSName from OperationsManager.dbo.MT_Computer where DNSName is NULL

2. Run the following SQL query to update the values of the DNSName of the cluster based on the NetBIOS Cluster Name, changing the values below to match your names:

     update OperationsManager.dbo.MT_Computer set DNSName = '<MyClusterDNSName>' where NetbiosComputerName='<MyClusterNetBiosName>'

After doing this restart the OpsMgr Health Service agent on the affected machines. After about an hour these symptoms should clear up.
