Cannot start error 127.0.0.1 - tried the fix, but still doesn't work

I've tried editing the "hosts" file, but I'm still experiencing this problem. Any solution? I'm on Windows 7.

Turn on the secondary Logon. The secondary logon service is a standard windows service which is available on every windows computer. In the latest versions it is not started automatically. You need to start it via control panel > administrative tools > services. Starting it once should insure it works in the future also.
