desktop locally and then you try to log on remotely, the local desktop locks automat-

ically and the remote user can then access all of the currently running applications

just as if she were sitting at the keyboard. If no one is logged on locally and you try to

log on remotely, Windows creates a new user session and you are then able to work

with the computer remotely just as if you were sitting at the keyboard.

Remote Desktop is not enabled by default. You can configure Remote Desktop

access by completing these steps:

1. In the Control Panel, click System and Maintenance and then click System.

2. On the System page, click Remote Settings in the left pane. This opens the Sys-

tem Properties dialog box to the Remote tab.

3. To disable Remote Desktop, select “Don’t allow connections to this computer”

and then click OK. Skip the remaining steps.

4. To enable Remote Desktop, you can select “Allow connections from computers

running any version of Remote Desktop” to allow connections from any version

of Windows, or you can select “Allow connections only from computers run-

ning Remote Desktop with network level authentication” to allow connections

only from Windows Vista or later computers (and computers with secure net-

work authentication).

5. By default, only users who have Administrator accounts on your computer can

connect remotely to your computer. You can manage access for other users

using the following techniques:

• To allow users with standard user accounts to connect remotely to your

computer, click “Select users.” In the Remote Desktop Users dialog box,

shown in Figure 20-11, click Add. Use the Select User or Group dialog box

to specify the user or group who should be granted remote desktop access

and then click OK.

• To revoke remote access permissions for a user account, click “Select users.”

In the Remote Desktop Users dialog box, select the account to remove and

then click Remove.

6. Click OK to save your settings.
