In Windows 7 and Vista, first open the Network and Sharing Center and click the Windows Firewall link on the bottom of the left pane. On the Windows Firewall dialog, make sure it's On, but do not check the Don't allow exceptions option.Ĭlick the Exceptions tab, scroll down, find the File and Printer Sharing option, and make sure it's checked. In Windows XP, open Windows Firewall from the Control Panel. However, you can manually disable the firewall rule or stop all network traffic, both of which would prevent your computers from communicating.

Windows automatically edits the Windows Firewall settings to allow file and printer sharing traffic through when you enable sharing.
