Did you export the necessary principals with ktpass.exe and add them to
melunarhttp.keytab with kutil copy?
The KrbVerifyKDC error sounds like there needs to be a host principal in
the keytab. The user=(NULL) OTOH sounds like theres a problem reading
the initiator's name from the initial Kerberos token or maybe it's an
artifact of not correctly exporting and importing the http principal
(in which case I would file a bug report regarding the lack of proper
I would get a packet capture and verify that the client is actually
doing the right thing (e.g. is IE properly configured to do integrated
authentication, the WWW server in the "intranet zone", etc).
