I had Dell, OME 2.01 working perfectly on a Windows 2008 R2 server. But we needed that server to run IIS 8.5, and I upgraded on demand to 2012 R2. The upgrade went flawlessly. BUT..now, no matter what I do, Dell Essentials fails to load. I've even uninstalled the app. even the database, even the IIS role, and still it doesn't work.
I do have a backup of the database, so, is my only option, to NUKE everything and then re-attach the database once it is done?
