If both the user name and server name resolve in the "Exchange Server"
service property sheet within the MAPI client profile, the issue is not
likely the firewall.

                Subject:        [FW1] MS Exchange 5.5 to work with
Checkpoint 2000


                Hello all --

                I am trying to configure my FW-1 to allow users from various
subnets
                (VPN and other local) to access an MS Exchange server I have
on a local
                segment.

                The Exchange server is running the Exchange protocol for
client
                access... So far, I haven't been able to connect correctly.

                FW-1 logs are showing no dropped packets (just a few on port
135
                *accepted* and then nothing else) but the Outlook (97 or
2000) fail to
                connect (Error: Outlook cannot open your default mail
folders -- Would
                you like to open your default file system instead?)

                I am thinking it could be one of a couple things:

                -- FW-1 is somehow dropping packets I don't know about

                -- I need to set up WINS in order for Exchange to
communicate with hosts
                on other subnets (but I don't think so, because I'm pretty
sure people
                can access Exchange right over the Internet if there is no
firewall).

                -- Something else??

                Does anyone have any experience with this kind of setup with
Exchange
                5.5?  I am running Checkpoint 4.1 SP2 under Linux.
Everything else is
                running fine.

                Also, I tried disabling the "silent service" drop, but that
did not
                improve the situation.  For now, my policies Are ANY ANY ANY
in both
                directions between subnets.

                Thanks,
                John
