PPP Installation and Configuration for Windows NT

Authored by: Kimberly Johnson, ECN

---

Windows NT Workstation includes Point-to-Point Protocol (PPP). PPP enables the use of TCP/IP over dialup connections (e.g., a modem). PPP configuration is very similar to the configuration of TCP/IP on a LAN adapter. The first step is to install the Dial-Up Networking component. Run Dial-Up Networking from My Computer. Please see Figure 1. To install the Dialup Networking component, open up the Dial-Up Network icon.

You will first be prompted to install the Dial-Up Networking component. You will need click on the Install button. Please see Figure 2.
