Hyper-V/Virtual Machine Manager 2008 (VMM) Uninstall

Over the last few months we have been playing with the Beta version of Virtual Machine Manager. A few days ago I decided to uninstall the beta version and install the RTM version. Since it was in our lab I was going to wait to reinstall, since I have some other things that needed my attention first. Well I was contact by a co-worker today about the VMs running on that server not behaving. After taking a look in the Hyper-V console we realized that the all the VM network adapters had failed to load.

We have had these machines up and running for some time now, so we know they have been working. This particular lab build is a single physical server running 2008 x64 bit, and Hyper-V. We installed VMM on this physical host to manage the VMs on the server along with an ESX test server and some minor Virtual Servers 2005 boxes. The tests have been running just fine the problems started with the uninstall.

Uninstalling VMM was a simple process, Control Panel - Add/Remove Programs. Once complete I uninstalled the consoles, admin site and was on my way. I verified that all the VMs were up and running (which they were), I could RDP to the server etc. The problems started when we noticed the above issue with the Network adapters. We attempted to restart the Hyper-V Services only to get an error complaining some files were missing. These are the services that wouldn't start...

We were getting

We rebooted the server and got the same results.
