SYMPTOMS
When you try to install a Microsoft Cluster Server (MSCS) server, you may receive the following error message:

The specified name is already in use on this network. You must enter a unique cluster name.

Note that you may receive this error message even though you are using a unique cluster name.



CAUSE
This issue can occur if the NetBIOS interface has been removed from the MSCS server.



RESOLUTION
To resolve this issue, add the NetBIOS Interface to your MSCS server, and then disable the NetBIOS Interface on the "heartbeat" network adapter:
 * 1) Click Start, point to Settings, click Control Panel, and then double-click Network.
 * 2) Click the Services tab, click Add, click NetBIOS Interface, click OK, click Close, and then click No when prompted to restart your computer.
 * 3) Apply the latest service pack previously installed on your computer, and then restart your computer.
 * 4) Click Start, point to Settings, click Control Panel, and then double-click Network.
 * 5) Click the Bindings tab, click All Adapters in the Show Bindings for box, and then double-click the "heartbeat" network adapter.
 * 6) Double-click WINS Client (TCP/IP), click NetBIOS Interface, click Disable, and then click OK.



STATUS
This behavior is by design.



MORE INFORMATION
If you perform multiple rebinds on the MSCS server, the bindings may not work properly. In this case, you may need to remove and then reinstall the Transport Control Protocol/Internet Protocol (TCP/IP) protocol.
