ERROR FIM 2010 R2 SP 1 AFTER UPDATE HOTFIX AND EXCHANGE 2013 CU 5

Hi All,

i have some issues in fim 2010 R2 SP 1 with the following environment ;

1.  2 server cross forest domain (OLD FOREST named old.local AND NEW FOREST namednew.local)

2. 1 server fim 2010 R2 SP 1

3. 1 msexch 2013 in forest new.local

4. 1 msexch 2010 in forest old.local

everything is ok before, after i made some changes in my server FIM 2010r2 SP 1 to latest hotfix (build 4.1.3599) and update exch 2013 to CU 5.

i got the following error.

my questions are :

1. what does the hotfix changes with the existing FIM Server, does it changes any customs (GAL, MA, etc) ?

2. is it related to exchange 2013 CU update ?

3. how to roll back them to condition before update (uninstall hotfix) ? are there any way to do that ?

kindly let me know, what should i do with this error.

thanks
