-
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\
Cause
This problem occurs because the Tunnel.sys file is missing. This file affects all the functions based on IPv6 transition technologies.
