I remember looking at this document when it first came out and not being
greatly impressed.
TBH I am sceptical of the whole server and domain isolation model as from my
experience it is actually very hard if not impossible to put the design into
practice unless the customers is willing to spend an awful lot of money to
invest in the time needed to define all the necessary elements. I've always
like the "security clarity" of this approach, but often fallen at the first
hurdle when looking at implementation.
Most companies (outside of MS corp) just don't seem to know enough about their
own infrastructure/environment to even begin looking at the SDI model - often,
it is hard enough trying to do internal firewalling with ISA Server and that is
just for a small subset of applications!!
Have anyone actually implemented an SDI design for a customer? Am I way off
base here or it is actually achievable???

Interoperability
Hi,
did anyone study are try out the guide
http://www.microsoft.com/downloads/details.aspx?FamilyID=589fcf8e-0511-4c22-
a39e-6b841dd3c74f&displaylang=en ?
I'm just starting to read it and it seems not to be very consistent! :-(
If I got it right the External network is the IPsec world (Isolation Domain)
and the Internal network is the non-IPsec world. The ISA is member of the
Isolation Domain.
I would expect a NAT relationship from the Internal network (non-IPsec
world) to the External network (IPsec world). However the procedure given
seems to reverse the direction!?!?
Further down the guide there is IMHO more inconsistentcy when they talk
about "Creating a Server Publishing Rule".
Hmm... I'm missing something???
