I have a few machines in my local network. A Mac running OS X 10.6.7, a PC running Windows 7 Pro, and a PC running Server 2008 R2.
- My Win 7 box can ping my server. It can't ping the Mac.
- My server can't ping the Mac or the Win 7 box.
- My Mac ping'd the server a few minutes ago, but now can't. It's never been able to ping the Win 7 box.
Everything is on the same network, same gateway, all through the same router. Mac and Win 7 are on wireless, server is wired. I am pinging only IPs.
I know this has to be a firewall issue somewhere on the line but I'm at a loss. Suggestions on where to start?
Edit: Another detail about the Win 7 box and server. I am able to remote into the server from the Win 7 box using the ip. I'm also able to mount a drive which is shared from the server on the Win 7 box. When a remote session is active, I'm able to ping the win 7 and server between each other. But when the remote session is closed, no more pings.
