I am in the process of setting up IPv6 on my network. I have about 10 Windows server 2008R2 servers and several windows 7 clients. I have two domain controllers each assigned a static IPv6 address and a DHCP server handing out IPv6 addresses. All other servers are using DHCP. My own Windows 7 laptop works fine to ping either of the domain controllers that have their static IP addresses. The servers return a PING: transmit failed. General failure. I think this is either a router advertisement issue or a DHCP server issue because I can give the other servers static addresses and they can then ping the domain controllers. So either I am being handed the wrong DHCP information, or the router advertisement is setup incorrectly.
I have a Watchguard firewall with advertisement on.
Any ideas would be appreciated.
