That's actually an interesting concept. I only have mail forwarders and
a sniffer in my honeypot dmz. Do you think that it is a good idea to
keep
a second domain in the DMZ domain? And what are some additional benefits
of
doing so?
Thank you,
Joseph

Well, I wouldn't say "no reason" like that... My FE ISA server is a
member
of the DMZ domain for the same reason. Of course, the DMZ domain and
the
internal domain don't have anything to do with each other-- but things
like
authentication and group policy are quite valid reasons to have even a
FE
ISA as a domain member. But I know you know that ;)

Hi Joseph,
Exactly. Since there isn't a net increase in the level of security
offered by the front-end being a domain member, there's no reason to do
so. What gets me are those who won't join the ISA firewall to the domain
because they're afraid men from Mars will come here and not get Measles.
