DNS cache poisoning is BAD

For those of you who do not keep up with the latest computer security events here is a "New Flash". It seems that some of the folks who run DNS on Windows machines have been having issues over the past couple of days with DNS cache poisoning. For those who don't know, DNS is like a phone book of the Internet. As we all know computers like numbers and we like names. So DNS translates those cool Dot-Com names to a number (IP address). Some vulnerable NT machines (NT and 2000) have a setting left on by default that allows someone to feed it bogus info and corrupt the DNS cache.

So if you wanted to go to American Express website you redirected to another web site.
