Chris,

Have you talked to your AD administrators?

What is the Active Directory Domain Name?
(You have obfuscated the names in you e-mail that makes it harder to spot
the problems.)


See if they have updated DNS with the service records that point at the KDCs.
On Solaris 10: /usr/sbin/nslookup
On Windows in a cmd window: nslookup:
  set type=ANY
  _kerberos._tcp.WHATEVER.COM
  _kerberos._udp.WHATEVER.COM

These should show the service records with priority, weight, 88 for the port and
the hostname of the KDC/AD. The information could also be added
to the krb5.conf file if needed. But check if they updated DNS as they should have.

P.S. Why would you want to use telnet? In you example of using telnet,
you would be sending your password over the net in clear text. Why not ssh?
