Endpoint Protection


When attempting to connect Advanced Threat Protection (ATP) to the Symantec Endpoint Protection Manager (SEPM) via the controller connection, the connection fails. Browsing to the RMM Webservices website (https://sepmip:8446/sepm) does not display the website even though the services are running.  

SEPM returned a non-200 HTTP response 


RMM Webservices were previously disabled by running ConfigSEPM.bat as outlined in HOWTO111804.  


Re-enable SEPM RMM Webservices using the following steps:

  1. Open a command prompt with admin privileges and navigate to the \Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\Tools folder
  2. Run the following command                                                                                                                                                                                                                 -ConfigSEPM.bat -RmmWS:ON 
  3. Restart SEPM and SEPM webserver service.
