I still don't understand the distinction between port and instance for
freetds connection.  If I connect using port in my .conf file, I can ask
the sqlserver what it's instance name is, but if I then try and connect
using that instance name it fails, ie

[mcdb]
    host = ntdevmog451
    tds version=8.0
    port=1433

lxdevws85 apps% tsql -S mcdb -U FUENV4\\fuadmin -P ful1ffe
locale is "C"
locale charset is "ANSI_X3.4-1968"
1> select @@ServerName
2> go

NTDEVMOG451
(1 row affected)
1>                              

Now, I put that name into .conf & I get

[mcdb]
    host = ntdevmog451
    tds version=8.0
    instance=NTDEVMOG451

lxdevws85 apps% tsql -S mcdb -U FUENV4\\fuadmin -P ful1ffe
locale is "C"
locale charset is "ANSI_X3.4-1968"
16There was a problem connecting to the server

This doesn't make sense.
