This is the problem.  Is the hostname you entered at the client prompt 
the same as the name
of the server that is stored in the KDC?  It may be a DNS issue, try 
specifying the
fully-qualified hostname when you make your connection from the client.

A look at the KDC logs might help clear this up.
