If you get this error, you probably have an error in the RAS files that control protocol connection to remote computers.
You have many options to solve it, I HOWEVER in my case a laptop with Windows 7, the easiest thing was to use the tool "RESTORE SYSTEM". The are in HOME -> ACCESSORIES -> SYSTEM TOOLS -> RESTORE SYSTEM
You must choose an appropriate point of restoration, since recent software uninstalls and reinstalls the installed that date.
The most likely cause could unconfigure RAS files are automatic windows updates.
