The Active Directory Domain Services service on Local Computer started and then stopped.

last day we installed Symantec Endpoint Protection (SEP) client agent in Primary Domain Controller on Windows server 2012 and its crashed within a second. We have other 4 domain controller on Windows Server 2003 r2 std working fine but as soon as installed SEP on Windows Server 2012 it crashed, however we uninstalled SEP with help of Symantec Technical Team but ADDS service still can not start. 

1) I am getting this error message on ADDS service startup.
