  • Outlook users disconnect after enabling front-end

    Hi,

    I have enabled my exchange ent. 2003/sp2 to be a front-end server in order to distribute push-mail to 6 other exchange 2003/sp2 std. servers (they will become back-end).

    this mail server has 3 active mail store + a pub store.

    When done some of the Outlook 2000 users (from different stores)are loosing connectivity to the store .Users with outlook 2003-2007 are not affected.

    Anyone has an idea???
    Thanks

    1. Try to find a common configuration for those Outlook 2000 stations:
    Office 2000 SP, Windows SP, AV, etc
    2. Try to update all those workstations with Microsoft update for Windows & Office.
    3. Check DNS & Wins connectivity.
    4. Try to create a new profile for test.
    5. Check that the Exchange servers are fully updated from MS updates including AV.

      Hi Tzachi,

      Thanks for your tips.
      Problem with outlook cleints solved after folowing the attached docoment : http://support.microsoft.com/?kbid=319175

      Now I have an issue with OWA not working for mailboxes located on the the front-end server itself.

      If anyone got an expirience with such topology fronend server with active mailboxes - any tips will be apritiated.

      Thanks.

        The FE + BE configuration was not created to host mailboxes on the FE, but only on the BE.
        This configuration was made to protect the mailboxes on the BE, so the FE will only transport data from and to the BE.
        In case of hacking your FE in the current configuration, the attacker will have access to the mailboxes.

        From security reasons, I'm sure its the best to move your mailboxes from the FE to the BE.

        * In general - verify that both FE + BE are installed with the same Exchange SP + Hotfixes.

          If there were mailboxes stored on the frontend server then it should not have been possible to make the server a frontend. It should have given you an error. Are you sure that you have mailboxes stored on the frontend server? If you do, move them to a backend server.

            Re: Outlook users disconnect after enabling front-end

            Hi All,

            For security reasons my exchange server is not really at front,but way back inside the LAN,users are passing (https only) throught the firewall (checkpoint)to the isa server (dmz)than to the exchange & it works like charm
            Issue is that I have few more exchange servers & I know that recomanded topology by microsoft is to buy an extra server+win lic +exchange lic...

            But there is a woraround...& this is what i am looking for.

            btw, currently when I enable front-end, active-sync stop working & I get an aplication log error(even ID 3031).

            Thanks Eran

              There is no work around.
              If you want to use a frontend server then the server must not have any mailboxes. If you don't have a frontend then all of your backend servers must be accessible by the ISA machine.
              No other options. No work arounds.

                Hi all,

                Eventually I deployed the solution as folow (without Exchange front-end at all):

                Users access single ISA server through diffrent public names via https ,all of the names point to a single ip address , can be different ip's as well.

                Than created dedicated active sync rules for each of my exchange servers.

                Thanks for the above posts.
