When attempting to change the "Network Proxy" setting within Symantec Endpoint Detection and Response (SEDR), the error "Network Proxy configuration failed!" is noted. Further review shows the SEDR appliance is listed twice instead of only once.
An internal error caused the All-In-One to be listed as a All-In-One and Scanner.
Remove the "scanner" so that only the All-In-One appliance is listed.
