[Users] Crashed controller node

I rebuilt the controller node for my oVirt environment and restored the DB. However, all running VMs now show up with a question mark and all storage domains and data centers show red. However, all VMs are running. How could I go about doing a complete fresh install of the controller and then connect it back up with the existing environment. I have found bits and pieces of the answer around the web, but nothing that clearly addresses this situation.
