Hi, I have two Win7-PCs. configured with ip addresses (Win7-1)2001::201f, and (Win7-2)2001::2122. and One DHCPv6 server configured in WIN2008R2. I am not able to get the automatic IPaddress from DHCPv6 server to WinPE pc. But in my network for the WIN-7 PCs I am getting the IPv6 addresses from DHCPv6 server. What are the things i need to setup for assigning ipv6 address automatically in WIN pe. Do i need to load any specific drivers etc? how do i verify all things are fine. I am able to ping using ipv6 address which i assigned to my WIN-PE environment to other WIN7 pc which in the same network. Is there any registry settings i need to do to make this ipv6 address getting automatically? Any suggestion please share. regards Haranadh
