How Do I ... Disable Ad Hoc Wireless Networking in Windows XP

Contents


Introduction

Ad-Hoc wireless networking (also known as peer-to-peer or computer-to-computer networking,) allows wireless devices within range to discover and communicate with one another. This can present security vulnerabilities, and negatively impact a user's wireless networking experience in the following ways:

  • Ad hoc networks allow communication with potentially malware infected systems; in essence promoting the spread of malware.
  • Man in the Middle Attack: Users with malicious intent may create an ad hoc network connection node to infiltrate or monitor connected computers, obtaining and destroying private data, while tracking all the network traffic you send and receive
  • Evil Twin: If you have previously connected to a peer-to-peer network, your laptop will then advertise it is ready and willing to host similarly named networks in the future. This can pose a problem for those connecting to you, preventing their network traffic from being relayed to the internet.

The configuration suggested in the procedure below prevents you from automatically connecting to any new, unknown networks and refuses connections to all ad-hoc networks.
