Symantec endpoint protection block active directory replication

Hi All,

As we have installed Symantec end point protection 12.1 on windows server 2012 but we are facing some issue.

Symantec endpoint protection is blocking active directory replication where our company user is facing lock account issue so please any one can suggest how we can solve this issue.

Please provide better soloution whereby windows server 2012 active directory can be run easily and dont be replicate.

Thanks
