Unable to load ADFS 2.0 in Windows Server 2.0

Question

I am trying to federate a domain in Office 365. The AD FS servers are running Windows 2012 R2 and AD FS appears to be working properly. The errors I receive are shown below.

I've not had this problem before when using Server 2008 R2.  What do I have to do to the AD FS server to make this work?

Answer 1

I'm going to answer my own question.  The following registry key and values were present.  There are blog and forum posts suggesting that this needs to be added, but they only apply to Windows Server 2012, not Windows 2012 R2.  Further, this
registry key and values were present on my servers even though I did not add them manually.
Removing this key, which removes the values underneath, solved my problem.
