You cannot rename an administrator who is created based on an existing user in the user source.
In ZENworks Control Center, click the Administrators tab.
In the Administrators panel, select the check box next to the administrator’s name, then click Edit > Rename.
Specify the new name, then click OK.
You can also use the admin-rename command in zman to rename an administrator account. For more information, see Administrator Commands
in the ZENworks Command Line Utilities Reference.
