kerberos logon to IP address

hello,

as I investigated the Kerberos implementation in Vista, Vista is NOT willing
to use Kerberos against an IP address. I was not able to make Vista uses
Kerberos against IP address not even by creating SPN for the IP address.

Although windows XP actually try to generate a ticket even for IP addresses,
and if an appropriate SPN is available, they receive the ticket, Vista
doesn't seam to do it under any circumstances, right ?

Vista just doesn't ask for a ticket for an IP address at all. Can this be
changed somehow?

many thanks.

ondra.
