| [Other] Windows 2008 ping issue
Hello Everyone,
I'm not sure if I should post it here or in IPv6 section but here goes.
I have a Windows 2008x64 DHCPv6 and DNS server setup with a static IPv6 address.
I setup another Windows 2008x64 system (PC1) as a test system.
For this system I enabled stateful mode by using netsh
netsh interface ipv6 set interface "Local Area Connection 2" advertise=enable managed=enable
So now PC1 picks up the DHCPv6 address and DNS from the server.
However when I try to ping the server I receive a
"PING: transmit failed, error code 1231."
The odd thing is that when I create a static IPv6 address
netsh interface ipv6 add address "Local Area Connection 2" fd00::1 now ping works.
Does anybody know why this works?
Someone else had the same issue here

| Probably belongs in the Networking forum or IPv6 forum - I have to assume the IPv6 forum exists, I have never seen it! 
Regardless, all I can tell you is that Error Code 1231 = "The network location cannot be reached"... |

What command are you using for doing your ping? Generally you will need to use the ping6 command to ping IPv6 addresses |

Santa Ana, CA | Ping6 is now part of regular ping in Windows 2008 (The Command is no longer there). I did try ping -6 as well to force IPv6. |

| Another possibility is that the host has been configured not to respond to pings (note that the IPv4 and IPv6 rules may be different if a firewall is involved). In this case the only alternative it to attempt a connection to a known open port and see if you can temporarily establish a connection. |

Santa Ana, CA | I turned off the firewall on both systems. I can ping using the local-link address. |

I figured it out! It seems for some reason my DHCPv6 server is not sending out the subnet prefix. I checked my routing table with netstat -rn and I did not find an entry regarding my fd00::/64 dhcpv6 prefix.
To those who want to add it in by hand
netsh interface ipv6 add route *IPv6Address/Integer(Prefix)* *Name of Interface* *Next hop* " (this can be changed how your network is setup. Like ::/0 to make a default gateway path)
More details on the command here

Thank you everybody. Had to combine what everybody said and use it as a hint... |
