In Lab, Windows server 2008 R2 are unable to communicate with each other

Issue : 
In my Hyper-v Lab, two machines are unable to communicate with each other.
Ping to destination IP show "Request timed Out" and when reboots ping shows "Destination host unreachable", which indicates the connection is being refused from the destination server.

Resolution : 
Properties of "Windows Firewall with Advanced Security on Local Computer" > Domain Profile Tab > Firewall State "On" and changed the Options "Inbound Connections" Block (default) to Allow.

this option is useful when you don't want to disable the firewall, alternatively you can make rules to enable the Inbound traffic from other server
