Welcome back. So far, we have installed and setup XenServer on a rack mounted server. We’ve also installed a guest OS. Part 1 can be found here, and Part 2 can be found here. Today, we are going to install a domain level ad-blocker. I’ve been working on this stupid part for months. Literally months. I’ve had absolute no luck until a few hours ago, so I wanted to write my steps down before I forget. This has been an absolute nightmare.
