PPTP is installed on a Windows NT-based server as a network protocol by using the Protocols tab in the Network option of Control Panel. You can add, configure, and remove PPTP by using the Protocols tab.
This section explains how to install and configure the PPTP protocol on a PPTP server and assumes the following:
· Windows NT Server version 4.0 is installed.
· One or more network adapters are installed. In most cases, two or more network adapters are required: one to connect to the Internet and one or more to connect to enterprise networks.
· TCP/IP is installed and bound to the network adapter connected to the private enterprise network, and the adapter is connected to the Internet.
· The network protocol used on the private enterprise network, (TCP/IP, NetBEUI, or IPX) is installed and bound to the adapter(s) connected to the private enterprise network.
· The PPTP server is configured with a static IP address.
· RAS, with Dial-Up Networking, is installed and configured.
· You know how many simultaneous connections with remote PPTP clients you want the PPTP server to support, so that you can configure the correct number of VPN devices.
· Configuring a computer running Windows NT Server version 4.0 as a PPTP server involves three major procedures:
· Installing PPTP and then selecting the number of VPN devices
· Adding the VPN devices as RAS ports and devices
· Configuring encryption and authentication options
