Symptoms

On a computer that is running Windows Server 2008 R2 Server Core, 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.

    Note By default, the Tunnel.sys file is located in the following folder:
    %windir%\system32\drivers\
