Attempting to add the DirectAccess role to a Windows Server 2012 domain controller today and kept receiving “There may be a version mismatch between this computer and the destination server or VHD”. I unchecked the Remote Access role and moved to the Features screen, went back to the Roles screen and checked Remote Access again and it worked. I think those are the steps. Some combination of back and forth in the Add Roles and Features Wizard ended up getting me past the error. Your mileage may vary.
Lighting for bands and DJs has come a long way since the non-grounded 120V household switches with hot electricity running right below your fingertips.
I’ve tested two lighting controllers and in the coming weeks and months I hope to post some reviews and primers on DMX lighting.
