E2750 Cmd Rej: UserID already logged on (or is logging on) another terminal

If a user is already logged on to a terminal, then the user cannot log on to another terminal. The user cannot change their password while being logged on to any terminal.

Recovery

1. Look at the scroll area of the terminal screen that is used for login.
   The following message is displayed: Info: UID is currently logged on (or is logging on) to terminal yy (where yy is in the range 1 - 16).
2. Find the terminal at yy and log off the user ID at that work station.
3. Return to the work station and resume the task that generated this error message.
