Installing PowerPivot for SharePoint on a domain controller

For several reasons I have recently been playing around with installing PowerPivot for SharePoint on various configurations. See an earlier post about taking PowerPivot off the network – learned that one the hard way when I took my laptop to the SharePoint Conference this month. Well, I ran into another one – installing PowerPivot on a domain controller. This one I don’t have 100% figured out, but I have a good workaround – and several people have been reporting this problem, so I decided to write up the solution/workaround in a posting.
