Not sure if I've heard anybody successfully running a pg *server* on
windows with kerberos, but I ru nseveral pg serverson linux with clients
on windows, using kerberos and AD.

This error message looks a lot like the ones you'd get if you have an
incorrect service name on the client. Did you change the name on the
client as well, or just in postgresql.conf? (Your steps seems to
indicate only postgresql.conf). The easiest way is to set the
environment variable PGKRBSRVNAME=POSTGRES.
