Filtering Internet access
*****Method one******
Pro's EASY TO DO. CON's NOT GOOD FOR LOTS OF CLIENTS.
How you approach this depends on how many users you are talking about, if its just a few users, the simplest way is to modify the host file on each PC and put an entry in it for each domain you DONT want the users to access and point them to 127.0.0.1 (you can edit the hostile with notepad or this, http://members.shaw.ca/tec
For example to block www.hotmail.com add this line to the end of the host file.
127.0.0.1 www.hotmail.com
NB in win 95/98/ME the host file is at C:\windows\hosts.sam (save it WITHOUT the. Sam extension and reboot)
In windows 2000 the host file is at C:\winnt\system32\drivers\
In Windows XP the host file is at C:\windows\system32\driver
*****Method Two*****
Pro's Easy to administer. CON's Expensive & NOT PRACTICAL FOR HOME USERS.
Give all your clients access to the Internet via a Proxy Server than can filter and block websites.
ISA Server http://www.microsoft.com/i
WinProxy http://www.winproxy.com/in
*****Method Three*****
Pro's Very scalable from home user to businesses. CON's Can Be Expensive
Use some third party software to do it for you.
