I looked for similar posts and didn't see any. I have two computers hardwired to a wireless router and one printer connected via wireless. When the firewall is enabled on both computers, they can't communicate with each other. Also, I can't print any documents from either computer to the printer. When both firewalls are disabled, everything is fine. I did go to the NETWORK tab and attempt to connect the two, but could not do it until the firewalls were disabled. I disabled the firewalls again and set up both of them on a network OK, server and regular. After enabling the firewalls there was again no communication between the two. I have Win 7 Pro and IS 2011on both boxes. Let me know if any more info is needed and thanks for any solutions. Walt
