Answers and Answers: Reasons and Solutions for Win7 System Cannot Access LAN

        In the past, under Windows XP, there was no problem in setting up the WAMP environment, but my new computer is Windows7. After the installation, I found that in the LAN, other computers could not be accessed at all. Is it a problem with Windows7? How to solve it?

Yes, Windows 7 comes with a firewall that blocks port 80 and needs to reset the rules. Open "Control Panel → System and Security → Windows Firewall", click "Advanced Settings" on the left, then click "Inbound Rules", then click "New Rule" on the right side, in the "Type of Rule to Create" Click "Port", next step, select "TCP", click "Specific Local Port" and fill in 80. Next, click "Allow Connection", then click Next; check the domain, private or shared according to your actual situation, then name the rule, and then you can let other computers access it.
