Active Directory Sites and Services
The long forgotten configuration of Sites and Services - amazing how many times its not actually configured, yet its the crux of Active Directory replication and control of rogue and uncontrolled logon traffic across your WAN links... Figured it would be a good time to document the basics on some of the configuration and why it should be done - not a hugely indepth article, but enough to give some understanding of how it works, why it should be done, and the problems you will get if you don't do it...
