2 Weeks ago I installed Symantec Endpoint Protection and Manager on the server that I also have OpManager on. Ever since I have done this the SEPP has killed OpManager, not allowing it to run. I contacted support on this subject and they logged into my server and shutdown the SEPP and then started OpManager and it worked but when I start the SEPP back up here is the message that I get from OpManager:

Please contact the server administrator, admin@india.adventnet.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
