If you are using SBS 2003 PREMIUM (with ISA 2004) then this is what I
suggest as I have also faced problems setting up SBS2003 with win mobile 6
device:
1. You need two certs:
Cert A- for "publishing.internal.local"
Cert B- for "gate.external.de"
2. You should Install certificate A on IIS.
3. Then open the ISA Server manager and open the web publishing rule
(tipically SBS Web Listener).
Open the "To" tab, and type "publishing.internal.local" as the server name.
Click to check "Forward original host header" and also click to choose
"requests appear to come from the ISA server computer".
4. You should install certificate B on the publishing rule on the ISA
server. Tipically the rule will be named "SBS Web Listener". Open that rule,
open the "Listener" tab, and then click Properties.
On the new window, open the tab "Preferences" and install certificate B
there. This is the certifcate that establishes the comunication between the
Device and the Server (certificate facing the EXTERIOR).
A good tip for troubleshooting ActiveSync issues is opening up Mobile
Internet Explorer on the Windows Mobile 6 device and open the website:
https://gate.external.de/OMA
This will spill out relevant troubleshooting information. As a general rule
if you can sucessfully connect to this site from the mobile device then
mobile sync will be working.
PS: You don't need to add the A-record for gate.external.de in your internal
DNS servers.

Hello,
I've got a problem and hope someone here has a solution for me :-)
SBS 2003 Premium
A smartphone (HTC Touch) with Windows Mobile 6 should get synchronised
with Exchange using Activesync.
For conntecing to the server a WLAN connection should be used on the local
workplace and GPRS connection when working outside.
My first problem was that the server is reachable from external under
"gate.external.de" but from internal "servername.internal.local" had to be
used.
Switching the addresses everytime manually on the mobile device was really
anoying, so i created a new dns zone on the the server with an "a-record"
pointing to the sbs ip.
That works well so far, you can use the address "gate.external.de" now
from the internal network, but there's a problem with the ssl certificate:
When "gate.external.de" is used from internal network, the ssl certificate
from "servername.internal.local" (publishing.internal.local) shows up, and
therefore the synchronisation does not work, cause Activesync see the
certificate as invalid (cause the certificate does not fit to the domain).
Hope somebody can help me, and sorry for my bad english :-)
Thank you very much!
Werner
