Cloud Management Gateway crashes CCMExec on Management Point (ntdll.dll 0x000409)
I am having a strange situation here and it even replaces on two environments that I host within the same Active Directory Domain.
The issue is the following: When I setup a cloud management gateway and a client tries to connect against it the cloud management gateway returns a 500 error. I checked the Management Point and realized that the SMS Agent Host was not running anymore and the Eventlog reported an Application Error 1000 Event with the following details:

The DMPDeviceCertAuthModule contains the following lines:
Anyone else facing this issue? I am running MCEM on a single server that may be the only detail I could think of that might be missing.
