After upgrading the Endpoint Protection (SEP) client to 14.0.1 MP1, if the option to 'Require a password to stop the client service' is checked, the user is prompted to enter an uninstall password when trying to uninstall the SEP client. When checking the policy setting, the 'Require a password to uninstall the client' is not checked.
Any of the three below Client Password Settings may be enabled.
The 'Require a password to uninstall the client' is NOT checked.
This issue is fixed in Symantec Endpoint Protection 14 RU1 MP2. For information on how to obtain the latest build of Symantec Endpoint Protection, see Download the latest version of Symantec Endpoint Protection.
Unchecking all of the the password options in the Client Password Settings option menu will allow the uninstall to complete as expected. The settings can then be returned to their prior configuration.
