When you publish a route to an interface on a Windows Server 2003-based computer that is configured as an IPv6 6to4 router, the 6to4 router service quits unexpectedly.
This issue occurs because the network stack disables the 6to4 interface when you add a 2002 address to the public interface.
By default, the 6to4 interface is disabled when you have a global address. When the 2002 address is added to the public interface, the stack recognizes this as a global address and therefore disables the 6to4 interface.
To work around this issue, manually set the 6to4 state to enabled. To do this:
Click Start, click Run, type cmd in the Open box, and then click OK.
Type netsh interface ipv6 6to4 set state enabled, and then press ENTER.
Close the command prompt.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
