When a user runs oslevel as root, it reports 4.2.1, but when the user is logged in as a user, oslevel reports 4.2.0.0.
There is something wrong with the .profile of the users. Create a brand new user, xxx, using the following command:
mkuser xxx
Then create the password for xxx. Log in as that user and run oslevel. It should report 4.2.1.0.
