Hi Grandeco,
The option to require a password to stop the client service refers to the
Symantec Management Client service (smc.exe) and applies to the user attempting
to stop the service by running the command line "smc -stop".
It does not apply to stopping services in the Services Control Manager
including Symantec Endpoint Protection . (Although you are
prevented by Tamper Protection from stopping smc because it greys out the
options). It also does not apply to disabling protection by right-clicking the
shield icon.
To disable SEP from system tray you would need to use the article Brian has suggested.
http://www.symantec.com/business/support/index?page=content&id=TECH102822 .
After following the above article found that "The Disable Endpoint Protection " won't be grayed out if the User is logged in as an Administrator or a Local Admin.
