Connections to SQL Server from a client running on the same computer use the shared memory and named pipes protocols. 
Shared memory has no configurable properties. Shared memory is always tried first, and can't be moved from the top 
position of the Enabled Protocols list in the Client Protocols Properties list. The Shared Memory protocol can be 
disabled, which is useful when troubleshooting one of the other protocols.
