And client and server agree on the name of the pipe?

Eh? Whether you configure a data source, have a program, or connect from
a tool like SSMS has nothing do with it. You can still set up the connection
to use TCP/IP. Usually TCP/IP is preferrable over named pipes.

Sorry, but I can't help more, because know next to nothing about your
machines. Are client and server on the same machine or different? Is the
instance a named instance or a default instance?

Did you check that the SQL Server Browser service is running and accepts
remote connections?
