Your multihomed Windows NT computers may experience name conflicts intermittently and Event Viewer may log the following event:
Event ID : 4320 Source : NetBT Description: Another machine has sent a name release message to this machine probably because a duplicate name has been detected on the TCP network. The IP address of the node that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.
The server service on your multihomed Windows NT computers is not releasing its registered NetBIOS name from your Windows Internet Name Service (WINS) server properly. Only the primary network interface card (NIC) is being released while the other NICs are maintaining the registration of the server service.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
