BES on Domino multi domain, crashing
 

I am having a problem with the Blackberry Manager crashing when browsing to a Domino server in another domain to add an account to the bES.

I have have a BES V4 running on Domino 6.54 in a multi (5) domain environment. The BES is working for 4 of the domains including one domain that uses a pass thru server to access it.

Domain A = BES
Domain B = Pass thru server
Domain C = Domain working using Domain B.
Domain D = domain crashing

Domain C & D are configured the same with Connection documents, Cross Cert and DA enabled.
Domain A and D can replicate and route mail between them using the pass thru server in Domain C.

The problem occurs when from the Blackberry manager, browsing to Domain D causes the BES Manager app, to crash with domino crashing as well.

I do not get as far as being able to browse for a user from the NAB on domain D.

Has anyone had a similar issue or any suggestions.
I will be unable to respond for a few days.

Thanks
