we have a 2012 server's nic showing connected to internet but cant ping 8.8.8.8


firewall returns Destination host unreachable though firewall can reach internet.
it can ping firewall. all other devices can reach internet.


i checked in the firewall and saw ping was allowed and packet was delivered.
safe mode is the same result


restarting the server and using another nic doesnt help.
this server is for exchange and although it cant send mail, it can receive.


anyone know how to fix it?


regards
