To resolve this problem, install this hotfix on the DHCPv6 servers that are running Windows Server 2008. After you install this hotfix, these DHCPv6 servers silently ignore unknown options in the incoming relay-forwarded packets. This behavior enables these DHCPv6 servers to issue IPv6 addresses to DHCPv6 clients through a DHCP replay agent.
