I upgraded Symantec Endpoint protection to 12.1.5 and windows could not start the SEPM which throws error 1069. The symptoms are specified in the KB: RL http://www.symantec.com/docs/TECH216042
However, I am unable to add user or group as described in the step 4. Is there a way to fix this error? I am running the SEPM on the DC which is a Win 2008 R2 server.
