Use Remote Desktop when Windows Firewall is on Because Windows Firewall restricts communication between your computer and the Internet, you might need to change settings for Remote Desktop Connection so that it can work properly. Click to open Windows Firewall. In the left pane, click Allow a program or feature through Windows Firewall. Click Change settings. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Under Allowed programs and features, select the check box next to Remote Desktop, and then use the check boxes in the columns to select the network location types you want to allow communication on. Click OK.
