Symptoms
When you issue a net view \\clustername command or use another NetBIOS connection on a Windows 2000-based Network Load Balancing (NLB) cluster by cluster name, you may receive the following error message:
System Error 52 - A duplicate name exists on the network.
Cause
NetBIOS connections to the virtual cluster name are not supported because the Server Message Block (SMB) protocol in Windows 2000 performs a server name verification. Server name verification does not work because clustername does not match the computer name of the cluster host that is receiving the connection request.
Status
This behavior is by design.
More information
To make a NetBIOS connection to a Windows 2000-based NLB cluster, connect by using the virtual IP address.
