i tried to put an exchange server 2003 front end in DMZ. and my ISA server contains DMZ.
but when i published the exchange server in ISA, my front end server can't communicate with the interne (back end one) because of DNS.
i put a rule to permit DNS trafic, it still bloked by the ISA, i don't know why?
any help will be gratefull!

Hi,

what´s the network relationship you´re using between these two networks?

I'm using ISA server 2006 between DMZ and my internal network.
The ISA server contains 3 NIC's, interne, externe and DMZ.
my internal network contains exchange back end server and Active directory, my DMZ contains the front end exchange server.
the front end server is published in ISA server, but it can't communicate with my internal network!!!
i don't know why!!

See one of my old posts her:

Don't forget to add the DMZ IP subnet to your AD Site configuration otherwise Exchange will not be able to find its GC and will moan about DSAccess problems...

Cheers

JJ
