how to block and allow sites through the host file

I need to be able to block users from accessing websites.

We have 3 websites we want to allow access to, but the rest to be blocked.

How do I do this.

I know there is ISA server but we only have sbs 2003 standard.

ive also looked at web filtering programs and they all look quote big and bulky.

ideally we would like to this through the server, but Im ok doing it on each client.

If they are limited to Internet Explorer this would work:

Winproxy might be in the cards for you then.

www.winproxy.com

It's not all that expensive and works very well.  Simple to use also.

Hmmm...I had no idea...too bad really.

If you're a hardcore tech, you may want to try SquidNT:

It's not simple, but it's free.

Or try CCProxy if you like/need a GUI.

SO is there no way to do it via hosts file

HOSTS simply redirects "blocked" sites to localhost (127.0.0.1) - you cannot include every site on the Internet except 3 - it's not practical.
