i cannot PING my VM in server 2008 r2

[troyquigley]

the vm can ping other computers
the host os can ping other computers
other computers can ping the host
but nothing can ping the vm

why ?

 

[tgabe213]

How did you create the virtual network for the VM? I'm assuming Hyper-V?

 

[troyquigley]

correct
just a standard (nothing fancy) vm


i set "public network location settings" to OFF for the firewall

and now i can ping the VM.

why is it that i can ping the HOST without doing this ?
yet the VM requires me to turn off the firewall to be able to ping it ?

Because the firewall for the host was adjusted previously in some manner. The deafult configuration for a Windows 2008 R2 server does not allow incoming ICMP traffic.

Installation of some features/roles change that.
