I spent a few minutes researching "Named Pipes" associated with the SQL Server Configuration Manager (and SQL Server as a whole). On the Wikipedia "OSI Model" page (http://en.wikipedia.org/wiki/OSI_model
) I found Named Pipes in OSI Layer 5. This confused me. I expected to find it in Layers 3 and 4 along with TCP/IP. I'd always considered Named Pipes to be an antiquated alternative to TCP/IP. But since it's Layer 5 and TCP/IP is layer 3/4, that doesn't seem to be the case. So what are Named Pipes with respect to SQL Server? How do I use Named Pipes with SQL Server?
