Step1: Go to your HOSTS file which is located at:
C:WINDOWSSYSTEM32DRIVERSETC  for windows Vista and XP
C:WINNTSYSTEM32DRIVERSETC for  Windows 2k
C:WINDOWS for Windows 98 and ME

Step2: Open HOSTS with Notepad.

The default Windows HOSTS looks like this:

# Copyright (c) 1993-1999 Microsoft Corp.

#

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

#

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one

# space.

#

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a ‘#’ symbol.

#

# For example:

#

#      102.54.94.97     rhino.acme.com          # source server

#       38.25.63.10     x.acme.com              # x client host

127.0.0.1       localhost
