Configure client callback options
Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 7
You can use this procedure to configure a remote access server to disconnect and then call you back to reestablish the connection from the server to you. This transfers the bulk of any phone charges to the remote access server, by having the remote access server dial back to your location after you initially connect. It also improves security when the remote access server is configured to call back only approved call back numbers.
Any user account can be used to complete this procedure.
To configure callback options on a network connection
Press ALT to display the menu bar.
On the Advanced menu, click Remote Access Preferences. The Remote Access Preferences dialog box opens.
In the Remote Access Preferences dialog box, on the Callback tab, do one of the following:
If you do not want to use callback, click No callback.
If you want to decide whether to use callback at the time you connect, click Ask me during dialing when the server offers.
If you want to use callback every time, click Always call me back at the number(s) below, and then select the modem or device you want to be called back.
If Phone number is blank for the device you have selected, click Edit, and then type the number.
If you want to remove a modem or device from the list of possible callback devices, click the modem or device, and then click Delete.
Dial-up server settings take precedence over the settings that you configure on client computers. For example, if you configure the client computer to request that the server call you back, but the server is not configured for callback, the client settings have no effect. Ensure that your server and client settings are coordinated to produce the desired results.
To use callback, Link Control Protocol (LCP) extensions must be enabled. For more information, see Start or stop requesting LCP Extensions in PPP.
