Problem with network connection from one computer to another. May be a firewall problem?
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 192.168.0.13. Let's call it C1. Computer C1 is an HP z440. Another computer on my network is 192.168.0.12. 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? Eset-seems-to-show-port-5939-as-open.PNG Firewall-shows-Tightvnc-open.PNG
