I am having a weird network issue. I have 4 virtualized servers (all Windows Server 2008 R2) on the same host machine. One of them, housing the management console and core of my backup and restore solution (AppAssure Replay), cannot be pinged. However, I am having no problem pinging out from it. I am able to ping the loopback address as well. I just applied a new GPO from my DC, but did the same on my other servers that are not having problems. All 4 servers also have the B/R client installed.
I am also having an issue with pinging my desktop (Windows 7 64-bit). Same thing as the server, TCP/IP seems to be working fine, I can ping out to any of the other machines (except the one server, of course), but cannot ping this machine from any other machine. This machine also has the GPO applied, but does not have the B/R client installed.
Anyone have any idea what could be causing this?
