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.
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.
To make a NetBIOS connection to a Windows 2000-based NLB cluster, connect by using the virtual IP address.
