SYMPTOMS
Consider the following scenario:
 * 1) You install the Microsoft TCP/IP protocol version 6 on a Microsoft Windows Server 2003-based computer.
 * 2) You use the Netsh.exe command-line utility to manually turn on the Forwards Packets and Sends Router Advertisements options for the Automatic Tunneling Pseudo-Interface.
 * 3) You restart the Windows Server 2003-based computer.

However, after you restart the Windows Server 2003-based computer, both the Forwards Packets option and the Router Advertisements option are disabled. For example, assume that you type the netsh interface ipv6 set interface  forwarding=enabled advertise=enabled command to enable the Forwards Packets and Sends Router Advertisements options. After the Windows Server 2003-based computer restarts, the Sends Router Advertisements and Forwards Packets options are set to NO.

Note In the previous example, you type netsh interface ipv6 show interface 2 at the command prompt to view the status of the TCP/IP protocol version 6 interface.



WORKAROUND
To work around this problem, create a startup script that resets the Forwards Packets option and the Router Advertisements option when the Windows Server 2003-based computer restarts. For example, create the following startup script:

netsh interface ipv6 set interface  forwarding=enabled advertise=enabled



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
