Explanation:
The Network Options extension allows you to centrally create, modify, and delete dial-up networking and virtual private network (VPN) connections. Before you create a network option preference item, you should review the behavior of each type of action possible with the extension.

To create a new Dial-Up Connection preference item
Open the Group Policy Management Console. Right-click the Group Policy object (GPO) that should contain the new preference item, and then click Edit.
In the console tree under Computer Configuration or User Configuration, expand the Preferences folder, and then expand the Control Panel Settings folder.
Right-click the Network Options node, point to New, and select Dial-Up Connection.
