  1. Click Start, point to Settings, and then click Network and Dial-up Connections.
  2. Right-click the icon for your ISP, and then click Properties.
  3. Click the Networking tab, click Internet Protocol (TCP/IP), and then click Properties.
  4. Click Advanced, and then click the Options tab.
  5. Click IP Security, and then click Properties .
  6. In the Use this IP Security policy box, click Client (Respond Only) or Do not use IPSEC.
  7. Click OK or Close until all dialog boxes are closed.

STATUS
