This should work. Can you connect with another client using the
instance? tsql?

I have encountered this problem with sql server when the SQL Server
Browser service is not started. The name is a bit confusing because it
is needed for clients to be able to contact with a named instance. If
this service is down, you can only connect with a port number. It
listens normally on port port 1434 and responds with the port number for
the instance.

Another option is to define the connection in freetds.conf. Something like
    host = server001
    instance = instanceABC
    tds version = 8.0

Don't specify a port when you specify an instance. They are mutually
