I researched the error code, and came up with this result:
1- go start->control panel->device manager open it
2- in view menu tick "view hidden devices"
3- open network adapters branch.
4- you will see many adapters named Microsoft 6to4. (i had over 150 number of them).
5- delete all.
6- restart your pc.
