If your server is indeed at the address and port described in you
freetds.conf, you will be able to connect to it with tsql.  If you
cannot connect with tsql, I suggest you use TDSDUMP to create a log file
and look at the output.  

It may be something simple, such as typing "127 instead of "172" for the
address (although I always recommend using names instead of numbers).  

Once tsql works, you've isolated the problem to DBI, which typically
works (with the right connection string).

Right.  That's the problem.  There is no server listening to 1433 at
that address.  If there were, you'd see a connect message.  

You may think there is a server there.  You may have been told so.  You
may be sure.  You may even be right.  But the test fails: you can't
connect to it.  Until telnet works, nothing will.  

Either the address is wrong, or the port is, or there's a firewall of
some kind interfering with the communication.  My money's on the port,
because it's not reported by Microsoft's tools, which you say work from
the same subnet.  You might try telnet from that Windows client, just to
be sure.  

HTH.  :-)
