SYMPTOMS

Attempts to bring a SQL Server 2000 or SQL Server 2005 virtual instance online on a cluster may fail, or the SQL Server virtual instance on the cluster may come online successfully, but the SQL Server virtual instance on the cluster will only listen on Named Pipes. Client connections made over Named Pipes will succeed, but client connections over TCP/IP fail.

The SQL Server error log reports the following error message if the Virtual SQL Server does not successfully bind to port 1433:

SuperSocket Info: Bind failed on TCP port 1433

If the Virtual SQL Server is set to bind to 0 or a dynamic port, the Virtual SQL Server still unsuccessfully binds and an error message similar to the following occurs:

SuperSocket Info: Bind failed on TCP port 0

This article discusses one possible cause of this error message. The information in this article helps only if you are experiencing this exact same scenario. For other possible causes of the error message, see the following articles in the Microsoft Knowledge Base:
