IPv6 transition technologies on Windows Server 2008 R2 Server Core

  • Artículo

If you are using an IPv6 transition technology on a Windows Server 2008 R2 Server Core installation you may experience one or more of the following symptoms:

•

IPv6 transition technologies such as ISATAP, 6to4 and Teredo do not work correctly when the computer is a member of a network.

•

You cannot see tunnel adapters for ISATAP, 6to4, or Teredo when you run the ipconfig /all command.

•

The CPU usage of the Svchost.exe process that hosts the IP Helper service (iphlpsvc) is abnormally high.

•

You cannot find the Tunnel.sys file on the computer, which should be under %windir%\system32\drivers.

If so, there is a fix available, see article 978309 (https://support.microsoft.com/kb/978309) for more details and the fix.
