Hello,
Despite meeting the prerequisites as documented here - https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-install-prerequisites#azure-ad-connect-server - the server had WMF 4 and .NET
This would not install using either Express or Custom settings.
It would fail at the point where you try to connect to your AD DS Directories and display the generic PowerShell message when a cmdlet is unavailable.
In this instance it could not find the cmdlet "Test-NetConnection" which was only added from 2012+
Is there a switch to put it in some kind of compatibility mode?
Is this introduced with the latest version and the enforced TLS 1.2 update?
I'd try an older version but they are not available.
Sam
