Gregg has tested KFW 2.6.4 with all of the CMU distributed and supported
applications without problems.

I have tested this code against Kermit 95 (telnet and ftp) and Eudora
(POP and IMAP) all without problems.  

There is something different about your machine.  The question to answer
is "what is it?".

A couple of diagnostic questions:

* Are you able to obtain tickets manually by requesting them with Leash?

* Do your application hang when you already possess a Kerberos 4 TGT?

* What are the contents of the KRB.CON and KRBREALM.CON configuration
files typically found in the directory specified by the %WINDIR%
environment variable?
