To enable or disable Internet Connection Firewall

1.

Open Network Connections

2.

Click the Dial-up, LAN or High-Speed Internet connection that you want to protect, and then, under Network Tasks, click Change settings of this connection.

3.

On the Advanced tab, under Internet Connection Firewall, select one of the following:

To enable Internet Connection Firewall (ICF), select the Protect my computer and network by limiting or preventing access to this computer from the Internet check box.

To disable Internet Connection Firewall, clear the Protect my computer and network by limiting or preventing access to this computer from the Internet check box.

 Note

To open Network Connections, click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections

You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. 

If you clear the Protect my computer and network by limiting or preventing access to this computer from the Internet check box, the firewall on your computer is disabled, and your network is vulnerable to intrusions.

You should not enable Internet Connection Firewall on virtual private networking (VPN) connections or on client computers because ICF will interfere with file and printer sharing.

ICF cannot be enabled on the private connections of the Internet Connection Sharing host computer.

Internet Connection Sharing, Internet Connection Firewall, Discovery and Control, and Network Bridge are not available on Windows XP 64-Bit Edition.
