Need to blacklist windows updates on 8e6
I work in a school's IT department. Recently windows automatic updates have been blowing up our allotted bandwidth. We have decided to blacklist/block windows updates on a mass scale by simply adding it to our blacklist in our 8e6 filter. The problem we have is that we're not sure what ip/url to use to block the updates. Sure, we could go computer to computer turning the automatic updates off but when you have over 500 computers, that's kind of time consuming. Thanks!
