The Sends Router Advertisements option and the Forward Packets option are set to NO after the Windows Server 2003-based computer restarts

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 number of the 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.

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:

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