I have 5 computers all running Windows 7 pro.  I have recently installed Eset Internet security  v13 home version on all the computers.
The problem:  I cannot connect to one computer.  All the others work fine.

Research I have done:  The affected computer is  Let's call it C1. Computer C1 is an HP z440.   Another computer on my network is  Let's call it C2.  I can ping from C1 to C2 .  I cannot ping from C2 to C1.  I have checked the network page in Eset.  See attachment.  I use Tightvnc and RDC to connect from C2 to C1.  I have checked the Windows 7 firewall .  See attachment.  
All the computers worked well before installing Eset.  And this problem only affects computer C1.  I can communicate to all the other computers.  
What must I do to get C2 to communicate to C1?
