This is not a secure way but you can add a line to C:\Windows\System32\drivers\etc\hosts like this:

Code:
# Copyright (c) 1993-2009 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 handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost

One system that I have used quite often is the service provided by OpenDNS.

This provides an alternate to the DNS servers used by default by your ISP, in addition, which relates to your request, is a site blocking service.

You can block sites by a general group - EG. all social networks or you can set it to allow one and block others.

The service is totally free for home users and is quick to set up, also as the blocking is done in the DNS server, and if you set the DNS settings in your router (password protect the Router administration page ). it is not changeable by the actual users.

Thanks, I used the very simple host file, it works fine and smooth.

Hi there
Most decent Routers in their security set ups allow you to block IP addresses.

This is IMO a better solution as this will work with ALL computers connected to your network --wirelessly or via a cable --whether Windows, Mac or Linux.

You also don't have to do anything if you re-install the OS either

Pic enclosed of Netgear router --others are much the same I'd guess.

You can also establish rules etc etc.

IMO blocking via the Hardware setup on the router is far better as a knowlegeable user could easily get round the Hosts file restriction by using a "Proxy" to access blocked sites if you've only done it in software.

Using Content filtering on the hardware would be much harder to "break" as the user would have to logon to the router in order to change anything. Hopefully you've secured THAT password.

The best way of all actually is to ONLY allow your users to connect to the internet THROUGH YOUR OWN PROXY but this needs a bit of set up and organisation.

Failing that I'd use the ROUTER's HARDWARE blocking mechanism.

The logs will also tell you what IP addresses were used so you can tighten up any "After the fact" security breaches too.

Cheers
