BO XI 3.1 : Active Directory Authentication failed to get the Active Directory groups

Dear all 

        In our environment, there are 2 domain (domain A and B); it works well all the time. Today, all the user belong to domain A are not logi n; for user in domain B, all of them can log in but BO server response is very slowly. and there is error message popup when opening Webi report for domain B user. Below are the error message: 

       " Active Directory Authentication failed to get the Active Directory groups for the account with ID:XXXX; pls make sure this account is valid and belongs to an accessible domain"

      Anyone has encountered similar issue?

   BO version: BO XI 3.1 SP5

   Authenticate: Windows AD

Thanks and Regards
