Hi all,I support 2 branches in South
Africa.Branch 1 =Small Business Server with
Exchange 2003 and ISA 2004 installed on the same
box.
Branch 2=Server 2003 Standard Edition with
Exchange 2003 and Isa Server 2004 installed on
the same box.

Now the branch with the small business Server's
OWA works internally and externally but the one
with the Server 2003 Standard edition only works
internally (localhost/exchange).i checked the
mail publishing rules are exactly the same
setup.Please help me as this is really
frustrating me.Oh and by the way For both
branches i am using http port 80.

Your help is much appreciated.Details below of
my allow rule in isa

General:Name-OWA
Action-Allow -Log requests matching this rule.

1). Move from having a static IP address to a dynamic one.

2). If your public IP address is now dynamic, then your name resolution from external locations is likely to be unreliable. Have a look at your router, and find out what your current public IP address is, then go to an external location, and try to go to https://xxx.xxx.xxx.xxx/exchange (assuming you have E2003). Note that you probably won't be able to reach this IP address from an internal location, because most routers can't reflect traffic back inside.

Please post back if you have any more problems or questions.

Hi there,thanx for your quick reply.I
actually do have a dynamic address.(Dyndns
account which i use to remote in and between
my branches.So what i do is remote into my
one branch and try to access my exchange OWA
from thereto the other branch.As i said it
works fine from the one branch to the other
but not from the other way around.Do you
think it has something to do with the fact
that the one server is a small businees
server and the other on a standard server
2003?The Isa mail publishing rules are setup
identically and the Directory Security and
everything in IIS is setup identically
aswell.I can log in successfully to the OWA
on the Small Business Server but not on the
Standard Server 2003???It doesn't really make
any sence unless i am missing something
somewhere.

I would try and reset the settings again and just go through the settings and see if there is something that is missing. Also make sure you have all of the updates installed. You say both are using ports 80, see if you can have one that uses another port number.

Please post back if you have any more problems or questions.
