I have exchange 2013 installed on win 2012 r2.
One day a technician came to install a * certificate and then we cannot access the management console.
When we connect we put the username and pass and nothing happens.
So I installed exchange on a virtual server with the 2 roles and finally managed to access the management console but unfortunately only for 2 day.
I think we have an authentication problem in the IIS.
Help please
