The other day I got a very worried request for support. Apparently the Forest and domain functional level of a Active Directory deployment could no longer be read. Nothing else was wrong, everything was working just fine. If I could have a quick look? So they shared the screen with me and this is what I saw.
And this …
Well that didn’t surprise me, they are supposed to be already on domain and forest functional level 2012 R2 as all their domain controllers where already on Windows 202 R2 for over a year. That error message is not right! After being puzzled for a moment when it hit me. This was a Windows 2008 R2 host without updated tools!
Once they used the correct version of RSAT or checking on a Windows 2012 R2 host all was show to be well and the scare was over.
Nothing so see here, move along.
