When the browsers are reset, you need to ensure that your browser will connect the right DNS while connecting to the site you need. Create a text file titled “hosts” on your pc’s desktop, then open it and fill it with the following lines2:
# Copyright (c) 1993-2006 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
# localhost name resolution is handle within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
Find the hosts.txt file in C:/Windows/System32/drivers/etc directory. Rename this file to “hosts.old.txt” (to distinguish it from the new one), and then move the file you created on the desktop to this folder. Remove the hosts.old from this folder. Now you have your hosts file as good as new.
