My first post here, so forgive me if I ask a questions that’s been answered a 1000 times before, but I'm having absolutely NO luck w/ Blackberry tech support getting things fixed...so you all are my last resort hoping someone has seen this before...

Problem: Initially the BES server will work flawlessly w/ all aspects of wireless synch, but after a random amount of time (usually between 6 to 12 hours) the BES server loses its ability to use MAPI to the Exchange 2007 server and thus all sorts of functionality is broken (Calendar synch'ing is the most common item). I know the problem has come back by opening the Blackberry manager application on the BES server, and am IMMIDATELY prompted for a username / domain and password. Furthermore, if i go into the "edit mapi profile" in the server config, I can't get the BESAdmin account to "resolve" w/ the check name button. A simple restart of the machine clears everything up, but again, only for a short amount of time.

My users are all fairly new to Blackberry, and I hate the fact that allot of them are wishing for their former Active synch devices back but honestly I can't blame them if they are missing appointments!

Setup:
- BES Server: Dedicated and fresh Server 2003 standard sp2 running BES 4.1.6 mr4. Running CDO 1.2.1

- Exchange: Exchange 2007 w/ sp1

- AD Setup: Two 2008 DCs both running a Global catalog in this site with the BES, a 3'rd 2008 DC with a gc in a 2'nd site


RIM i think is at the point of throwing their hands up and saying its an AD problem or an issue not being able to reach a global catalog server..but i would tend to believe I'd see other strange behavior out of other servers in my enviroment if the GC's were just flaking out periodicaly. I've also reviewed the event logs of the DCs and found nothing incriminating on those ends...

ANY thoughts or ideas would be IMMENSLY appriciated!!

Have a look at the MAGT log, somewhere in the first 100 lines, it should say something like:

Check if that GC is really running properly. Also, more down in the MAGT log, check if you see any errors relating to GC connectivity.

obviously this is part of the problem...from yesterday the 7'ths MAGT log

[30000] (04/07 14:22:09.510):{0x138} [ENV] Failed to open reg key Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\BlackBerryServer\dca740c8c04210 1ab4b908002b2fe182 to retrieve the Global Catalog Server (GCS).

I asked BB tech support about that key yesterday and why there was no GC entry there in the key...they informed me that there wouldn't be due to me running Exchange 2007...but somehow im thinkin that may not be the right answer

if not tried already, uninstall and reinstall Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1

what account did you use to install BES ? check that account has a valid mailbox in your exchange, open it up in OWA ?

Can you check permissions for this account on your exchange and on your AD ?
check this link for BES and Exchange 2007 setup Exchange 2007 BES Install Guide - 100% Fully Functional

read a little on this thread
Reboot of AD breaks BES till service restart

SoUncool - Already tried un-installing /re-installing both CDO and the BES software on a whole. Both installed as the "BESAdmin" acct. I've opened its mailbox just fine as well.

knotty -

Your thread is almost EXACTLY what i need..but a few questions after reading the entire thread..

1. it sounds like you had almost the identical problem i had...except I'm not restarting (that i know of) any of the GCs. did you end up applying the ex2003 hotfix ? I'm weary of doing that as we run EX2007 and no 2003 management tools on the BES server obviously (since using CDO 1.2.1)

2. The turning on of GC refferals...is that what you ended up doing?

I'll re-read a 2'nd time your thread for more clues i may have missed

Yes I added the regedit and have been able to reboot my DC/GC and BES recovers so far. It used to recover before that too, knot that I reboot it very often.

Any ideas why the server wouldn't actually have anything in the DCA key though?

and then this is what the DCA key looks like


[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\BlackBerryServer\dca740c8c04210 1ab4b908002b2fe182]
"00036639"=hex:01,00,00,00

It was that way for a long time on mine.

Only recently did I do the fix that was mentioned in the thread I posted about.

And just to clarify, your refering to this correct?

Have you tried rebooting/registering the .dll's before you install the BES?
