SQL4-00-034200 - SQL Server must disable communication protocols not required for operation.
Having unnecessary protocols enabled exposes the system to avoidable threats. In a typical installation, only TCP/IP will be required. NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
In SQL Server Configuration Manager, right-click on each enabled protocol that is not required. Select Disabled. Close SQL Server Configuration Manager. Restart SQL Server.
