More specifically, would the net_transport column tell me this?
MSDN (here) indicates that column "Describes the physical transport protocol that is used by this connection."
Running a quick select against the DMV I see mostly TCP, a couple "session," and a few "Shared memory" (which when joining to sys.dm_exec_sessions show these are from the SQL server itself.)
We're supposed to have Named Pipes disabled, yet it is currently enabled on this server...
Thanks
