Help,ID Host file

I found this file in C:\Windows\System32\Drivers it is a host file. Inside it's in a note pad ,,,,,, 170.0.0.1 Local host ,that's it nothing else. What is this file and what is it used for.

 

Check out this link it may be of assistence. http://www.mvps.org/winhelp2002/hosts.htm

 

On Windows NT/2000/XP/2003 systems the hosts file is located in C:\Windows\System32\Drivers\Etc. On Windows 3.1/95/98/ME systems the hosts file is located in C:\Windows\Hosts.

If your hosts file is located anyplace other than the above loactions of your specific system, it should be deleted.

To rester your hosts file to the Microsoft default hosts file:

Please download HOSTER and then follow the below steps.

• Unzip Hoster to a convenient folder such as C:\Hoster
• Run Hoster.exe, click Restore Original Hosts and then click OK.
• Click the X to exit the program.
