Can't see network printers or computers

Hi, I have a domestic network at home, and since I had installed CIS (I do not changed any settings), my computer is not able to see any of the others computers or printers in my network. What should I do so I could see my network devices?

Make sure network discovery is turned on in windows advanced sharing settings, disable block fragmented IP traffic advanced firewall setting in comodo. You could also set the network you are connected to as trusted by going to firewall tasks manage networks and select trusted and ok out the window.
