Front End-Back End Problem
|

| Frank Durham 2002-10-05, 8:28 pm |
| Greetings-
I have installed a FrontEnd - BackEnd topology in our infrastructure. The
Front End server sits in our DMZ, our Back End Server sits in our protected
network. Our Exchange 5.5 server sits in our DMZ. I installed the Front
End server first while it was in the protected network. The installation
went fine and then added SP3 and that installed fine. Installed the Back
End and SP3 and both installed fine as well. I moved the Front End server
to the DMZ, changed the IP address, changed the DNS and WINS entries in the
Protected domain to reflect the new IP address. Created LMHOST and HOSTS
files pointing to the Domain Controller in the protected network. When the
machine boots, Information Store, System Attendant and MTA Stacks services
will not start. Now I opened up the following ports on the Pix Firewall so
the Front Server can talk with the DC.
389 TCP & UDP
135 TCP
88 TCP & UDP
53 TCP & UDP
691 TCP & UDP
3268 TCP
IS there anything I am missing?
I check with technet and all the articles basically point to ports that need
to be open. But I also opened up all ports and still services will not
start.

| i don't know about exch 5.5
i have the same setup with exchange 2000.
and thos ports i opened them in the DMZ->internal LAn direction only and
everything works fine.
there is no need for lmhosts, nor host, and having wins on dmz is not
recommended....
yo u must put in you rinternal lan DNS server a static mapping for the new
ip of the dmz server.
also you need to edit a registry key so that RPc uses a spaecific ports
inestad of the random >1024 one
search for a doc named e2kfrontend.doc in MS exchange site
