This is an enhanced version of Example 1. Instead of only 1 WXP-Pro-PC you have at least 2 WXP-Pro-PC's with the XP Unlimited software.
The problem is that, although you are using firewalls and virus scanners, and all your Windows-PC's are uptodate with all the patches, you still might run into problems because of viruses.
A virus is always a problem, but a virus on your important server with your business software is even a bigger problem.
One WXP-Pro-PC will be used for the business software. You have configured this WXP-Pro-PC in such a way that it is not allowed and it is not possible to use a browser, email or internet in general. This system might also act as a file- and printerserver. The firewall on this system is not only configured for protection against problems coming from the internet, but it will also filter or block any undesired access from internal systems. Not a single other system is to be trusted.
The other WXP-Pro-PC is only used for internet and email. There is hardly any user-data on this system. In case things go wrong, format C: will fix the problem.....
