My first question is why do you have to have it in the DMZ, but it seems you
were being told to put it in the DMZ.

Can you show us the URL's you referenced in setting this up.
I assume you are running Exchange 2000 on Windows 2000 in an AD Domain?

What exactly is your front-end? Is it the Outlook clients or is it Outlook
Web Access?

Not sure what you mean by this:
' I mean all I am trying at the moment is to connect to our internal Domain
by accessing the network ID in the My Computer properties and trying typing
in the Domain.'

Are you using a computer in the DMZ running Windows 2000 Professional and
trying to login into your Active Directory Domain?

Hi guys,

I've basically been told that we require an Exchange
system operated within our DMZ setup. After much
reading I've decided to go for a front-end, back-end
Exhange system, with the Exchange front-end in the DMZ
and the back-end in the LAN. However, even though I've
opened up all the ports specified in MS' white papers
between the DMZ and LAN, I cannot connect to the
domain/active directory from the Front-End server. How
do I go about this? I mean all I am trying at the
moment is to connect to our internal Domain by
accessing the network ID in the My Computer properties
and trying typing in the Domain. Do I have to do
anything else?! Sorry for my amateurishness(!) but
we're a small firm and cannot afford a fully-fledged
exchange specialist, thus I'm doing it!

Thanks in advance.

Dean Pullen.
