Your computer is connected to a network that supports IPv6 connections, but fails to be assigned an IPv6 address using DHCP. Your Internet Service Provider (ISP) may indicate you have a duplicate DHCPv6 DUID and point you to this article for resolution.
In November 2012, Microsoft released updates on Windows Update to resolve this issue:
Delete the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters\Dhcpv6DUID and reboot the computer. To do this, perform the following steps:
Open Registry Editor
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters
Right click and delete the entry named Dhcpv6DUID
Reboot the computer
NOTE: Please ensure that you make a backup of the registry / affected keys before making any changes to your system.
