Blocking sites from browsers (1 Viewer)

[Chxta]

My boss asked me to prevent some members of staff having access to the Internet. Normally that would mean creating an access list on the server and removing them from it. However what he meant was that they should be able to access the company's intranet, access their emails (official emails) and a few other things which have to be done online.

This means that one should limit the access on the individual system, for the browser only. The following is how it could be done in both Internet Explorer and Firefox. I think it would prove useful when my kids come of age...

1. Copy the text below and paste it into Notepad:

((PICS-version 1.0)
 (rating-system "http://www.microsoft.com") 
 (rating-service "http://www.microsoft.com") 
 (name "Noaccess") 
 (description "This file will block all sites.") 
 
 (category  
  (transmit-as "m") 
  (name "Yes") 
   (label 
   (name "Level 0:   No Setting") 
   (description "No Setting") 
   (value 0) ) 
  (label 
   (name "Level 1:   No Setting") 
   (description "No Setting") 
   (value 1) ) ))

Name this file 'noaccess.rat', and make sure that it is a normal ASCII text file. Save this file into the C:\Windows\system32 directory...

2. In Control Panel, double-click to open the Internet Options icon, and then click the Content tab.

3. Click Enable.

If the Enable button is not visible, and you only see the Disable button, then Content Advisor is already enabled and you should stop now or risk losing all your existing settings. If you wish to continue, then click the Settings button in place of the Enable button.
4. On the General tab, click the Rating Systems button, and then remove all the existing rating systems entries.

5. Click Add, and then click to select noaccess.rat.
6. Click OK to close the Rating Systems window.
7. Select the Approved Sites tab.
8. Add only the sites that you want users to be able to access, and then click the Always button.

All other settings should be left at their default settings. If you have used Content Advisor before and made any changes, there are two settings that must be put back to their default values.
9. Click the General tab, and make sure that under User options, the setting Users can see sites that have no rating is not checked.
10. Click the Advanced tab. Under Ratings bureau, set the Ratings bureau list box to [None].


If you use Firefox, just download the BlockSite plugin, and you are in business.

Edit: the boys aren't happy with this new state of affairs at all.

er... why not add the relevant blockage in the firewall? much, much cleaner than messing with their desktops

your company has a firewall, yes?

There are no defined workgroups and the network is set up to DHCP, so the addresses change all the time. Was asked to implement the changes immediately on four systems, so I found it easier to just RDC into them as Admin (using their addresses at that point) and implement what I described above...
