Excerpted results from PowerShell query:
PS C:\Windows\system32> Get-AdfsSystemInformation
OSVersion : 6.2.9200.0
OSName : Microsoft Windows Server 2012 R2 Standard
MachineType : VMware Virtual Platform
AdfsVersion : 2.0
PS C:\Windows\system32> Get-AdfsVersionEx
2.0
I have read several places (the actual quote) (a second reference) (a third reference) at AD FS 3.0 conforms to this statement: "the file "C:\Windows\ADFS\FSConfig.exe" DOES NOT exist (but the folder "C:\Windows\ADFS" does)". This is true for my server.
It does say Installed.
PS C:\Windows\system32> Get-WindowsFeature ADFS-Federation | FL InstallState
InstallState : Installed
The operating system version 6.2.9200 is Window Server 2012 R1, not R2. You need to provide the output of the PowerShell command:
Get-WindowsFeature ADFS-Federation
. If it doesn't say installed, I would speculate that server was an inplace upgrade from 2008 R2. The built-in ADFS version for Windows Server 2012 R1 is 2.1. The built-in ADFS version for Windows Server 2012 R2 is 3.0.
