If you must wake computers on a dierent subnet, you may want to use a computer
on that subnet as a sentry. The sentry computer never sleeps, it runs another licensed
copy of Remote Desktop, and it allows itself to be controlled by your local copy of
Remote Desktop. You control the sentry computer and instruct it to wake client
computers on its local subnet.
To wake a computer:
1 Select a computer list in the Remote Desktop window.
2 Select one or more computers from the list with a current status of “Sleeping,”
or “Oine.”
3 Choose Manage > Wake.
4 Click Wake.
Locking a Computer Screen
Apple Remote Desktop can lock a computer screen. When you lock a computer screen,
no one can see the desktop or use the mouse and keyboard on that computer. By
default, Apple Remote Desktop displays a picture of a padlock on locked screens, but
you can display a custom picture. For more information, see “Displaying a Custom
Picture on a Locked Screen” on page 147.
You can continue to work with computers using Remote Desktop after you’ve locked
their screens.
To lock a computer screen:
1 Select a computer list in the Remote Desktop window.
2 Select one or more computers in the selected computer list.
3 Choose Interact > Lock Screen.
4 Enter a message to be displayed on the locked screen, if desired.
5 Click Lock Screen.
The client screen goes black, except for the administrator’s name, the default picture,
and any message text.

You can display a picture of your choice on the client screen while it is locked by Apple

computer’s screen. For example, if you have clients with 800 x 600 screens, a picture
that is 1024 x 768 is scaled down to t the screen.
To create a custom locked screen picture:
1 Create a picture using a graphics program, such as AppleWorks.
