Not to be pedantic, but I think it's helpful to distinguish: the above
is telling you that the client connected to the server.  The login
packet was sent to the server, and the server rejected it.
You're connecting; your network settings are OK.  You're just not
logging in.

Instead of a login acknowledgement, 
the server returned an ERROR packet, type 0xAA.

The text of the message in the error packet was reduced by 50% because
it arrived as UCS-2 and was converted to a single-byte encoding,
perhaps UTF8 or ISO 8859-1.  The message was forwarded to the client
handler, which eventually gave it to PHP, where I believe you saw it.

What kind of authentication is your server set up to accept?  If it
doesn't accept a plaintext login, you'll have to link FreeTDS to
Kerberos.  I would look in that vicinity.
