Ping problem and Card Network

[Wajeeh]

Hi,

I have this problem:
I have a PC (COMP-A) that can ping by itself to the outside and so far is good!
If the server Ping COMP-A is as if it were disconnected ...and gives the request expired...

I tried uninstalling and reinstall the network card, nothing to do, disable and reactivate firewall, nothing to do, I looked in the windows of services linked to the network and all seem to place (at least those are set by default !), I have replaced the integrated network adapter (off) with an additional network card, I put the IP I did a test and nothing to do!

Thanks in Advance

Is that uses firewall as its security?

Why not use the firewall PC in a domain is managed by an outside company that has as a firewall domain WatchGuard.

I think it is not a hardware problem, if the network cards work in both the COMP-A and then the server must be a permissions issue.

How are connected to the COMP-A and the server?
