There have been several different Front-End Back-End whitepapers, are
you following the one from :

 http://www.microsoft.com/downloads/release.asp?releaseid=43997

It is one of those new Book format whitepapers.

Thanks

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?

Subject: Exchange in the DMZ

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 IFront-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.
