Here was the deal for me.....I just got off the phone with RIM support. There is 2 windows folders that you need to clear out as well as the registry hack. And there is an updated registry hack as of yesterday....but it is only a reg hack for SP2...and SP2 has not been released...so not sure what the hell they are doing...here is the link if you want to look at it:

As far as the Windows folders....Navigate down through whatever drive you installed BES on...for ex. C:\Program Files\Research In Motion\Blackberry Enterprise Server, and go into the Agents folder and then APBData folder. Delete anything in this folder. Now you need to go into the Install location for Domino....navigate to where you have your Domino Data directory. Go into the BES folder and then APB folder. Delete everything out of this folder. Restart your server and it appears we are not receiving an APB's now. We were getting about 100 APB's as soon as we started Domino and BES and the last restart after we did this no APB messages were sent out. I have my fingers crossed that this continues to work...
They also verified that SP2 would have some functionality to turn APB's on and off. We will see.
Hope this helps...I know this is probably the #1 complaint for BES Admins....what a headache!!!
