WinRM Operations over HTTPS fail with Access Denied for some systems
You are unable to perform some tasks that use WinRM when using HTTPS. The attempt returns an access denied. The same tasks succeed when using HTTP.
An example of such a task is using the “new-pssession” Powershell cmdlet. The symptom is not limited to this Powershell example as the underlying issue could manifest for any operation attempting to use WinRM over HTTPS.
