You cannot configure DHCPv6 stateless mode to be used by a Windows 8-based or Windows Server 2012-based computer

Symptoms

Consider the following scenario:
  • You have a computer that is running Windows 8 or Windows Server 2012 in a network environment.
  • You have an IP version 6 (IPv6) router in the network environment.
  • The router sends a Router Advertisement message to the computer. The Router Advertisement sets the DHCPv6 mode to stateless mode.
In this scenario, the computer does not change to DHCPv6 stateless mode, and instead remains in stateful mode. Therefore, the computer cannot obtain some additional network configuration parameters from a DHCPv6 server, such as the DNS server address.

Cause

This issue occurs because the settings that specify the stateful mode are cached. Therefore, the new configuration is not applied.

Resolution

This hotfix is also available at Microsoft Update Catalog.

Hotfix information

After you install this hotfix, the "Managed Address Configuration" setting and the "Other Stateful Configuration" settings are set to their default values (M=0/O=0) when you configure a device to behave as a router by turning on the Router Advertisement. The administrator has to reconfigure the settings by using the netsh command according to preference.

Workaround

To work around the issue, reset the IPv6 configuration state by using the following command:
netsh interface ipv6 reset 

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More Information

When you use the DHCPv6 stateless mode in a network environment, an IPv6 router sends a Router Advertisement message to set the managed flag (M) to 0 and the other flag (O) to 1 (in other words, M=0/O=1). When a DHCPv6 client computer receives the Router Advertisement message, the client computer sets the DHCPv6 mode to stateless mode (M=0/O=1).



When you have a Windows 8-based client computer in a network environment that does not have an IPv6 router, no Router Advertisement message will be sent. In this situation, the DHCPv6 client computer sets the DHCPv6 mode to stateful mode (M=1/O=1). This status is cached on the client computer. When the client computer is moved to a network environment that uses DHCPv6 stateless mode, the status cannot be changed from stateful mode (M=1/O=1) to stateless mode (M=0/O=1). Therefore, the client computer cannot obtain some additional network configuration parameters such as the DNS server address.
