When you create a Network Name resource, the System event log contains:
Event Type : Warning
Event Source : ClusSvc
Event Category : Network Name Resource
Event ID : 1149
Description : The DNS Host (A) and Pointer (PTR) records associated with Cluster resource <ResourceName> were not removed from the resources associated DNS server.
If necessary, they can be deleted manually. Contact your DNS administrator to assist with this effort.
The above warning occurs when the Network Name resource is created and not yet brought online on the node that is hosting the resource. The name is not yet registered in WINS or dynamic DNS.
When the resource comes online, the DNS and WINS entries are updated.
NOTE: You can safely ignore the above warning.
