Hi,

We setup ADSSP in an test envrionment to see if it's fits our needs. We successfully be able to setup MFA on some endpoint (Windows 2019).  One of our test server is the DC (the only one) of the test domain with Windows 2012 R2 installed.

When we try to connect on it we got this window appears instead of having the MFA choice :

On the server we can see error in EventLog about ADSSPProvider64.dll crash.

There's anything special for Windows 2012 or Domain controller?

P.s. Our server are in french.
