Hi Joseph,
OK, when I do the remake, I'll make them left to right :-)
Yes, for the most trouble free and transparent config, make the Internal
and external domains the same name. External hosts will only access your
public records, which will only be for things like mail (A and MX), www,
ftp, etc. Then you create the appropriate records for your Internal zone
that goes by the same name. External hosts never access the Internal
zone, and Internal hosts never access the external zone.
Once you have it in place, you'll never go back :-)
HTH,
Tom

Hi Thomas,
Yes sir, I've read all of those goodies. You even mentioned the split
DNS setup.
Like a good techno-dude, My setup is already in place and I'm wondering
how much Work it will be to get things working. I actually plan on
reformatting all my machines Over the next month and redo the internal
network. Maybe at that time I could change the name.
So, your basically saying that if my external mail machine is
mail.somesite.com That my internal DNS for that machine also needs to be
mail.somesite.com?
I nice picture form left to right might help solve this. Or, at least I
like pictures of Network diagrams that go left to right rather then top
to bottom! <grin>
I actually thought that the message screener was interfering with the
setup.
Thank you,
Joseph

Hi Joseph,
The split DNS is an absolute key to making this work. The name of the
Exchange Server needs to match the host name used to access the machine
from the remote host, and the remote host needs to correctly fully
qualify the NetBIOS name. I think I've written about this ten times, and
I'm preparing to write about it again, since you can't say the same
thing often enough, in different ways, when the thing being said it
really important and really often misunderstood.
Check out the DNS stuff in the various kits and the Outlook client
configuation sections. There's coverage in those docs on the DNS client
configs.
HTH,
Tom

http://www.ISAserver.org
Hi All,
I've re-read the articles on ISAServer.org and decided to add back in
the capabilities to utilize Outlook clients over RPC to connect to my
exchange machine.
I run a back to back network. All machines are w2k boxes. I've not yet
moved all over to windows 2003. My DNS machine in the DMZ hosts many
sites and has a different Name then my DNS server behind my second
firewall.
My external ISA box has the message screener running and forwards all
SMTP mail to a relay box. So, I setup the Exchange RPC rule to point to
my internal ISA machine. I'm not sure if by pointing to the different
sources has any affect on connecting with outlook client. SMTP mail is
arriving as setup.
I know that for the blaster and sasser type scripts it disables access
to ports 135(outbound) and 445.
What is the best way to trouble shoot this type of setup? I'm unable to
connect from an external outlook client, message is that global address
book not available? And can't find exchange. I don't' see any particular
messages in the log files to pinpoint connectivity issues.
Thank you,
Joseph
