Disabling Dial-Up Server Support

You can prevent users from remotely accessing computers even if a remote connection has been previously established. You can restrict access by making direct changes to a computer's dial-up support capabilities or by using System Policy Editor to create a policy file.

To disable the Dial-Up Server on a single computer

1. From the Connections menu in the Dial-Up Networking window, click Dial-Up Server.
2. In the Dial-Up Server dialog box, click the option named No Caller Access.

You can disable dial-up support on each computer or on a system-wide basis by using System Policy Editor to change a single computer's Registry or to define policies that can be shared by multiple computers.

To disable dial-up support by using System Policy Editor, and enable the option named Disable Dial-in.

The Dial-Up Server menu option still appears on the Connections menu after dial-up support has been disabled, but no dialog box for setting up the dial-up server will appear. For more information, see Chapter 15, "User Profiles and System Policies."
