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?

So Eset is the issue here. Then I would compare the Eset configuration with another computer.

I am not a computer expert. I don't have lots of knowledge about networks or ip addresses.
All the computers have static ip addresses which start with 192.168.0. etc.
All have the same work group name.
I log into each computer with the same login name and password.
What configuration differences would you be looking for if you were solving this problem?
What utilities might be useful to solving this problem?

Because Windows Firewall is managed by Eset, do one more test. Disable Eset but enable Windows Firewall on both ends.
Btw. Is there something like Firewall settings?
I would open Eset settings on both computers and verify there are no configuration differences (for instance: Connection Settings).

Thank you all for your help. Eset sent me a message describing what to do.
