When I logon my Server 2012 R2 server via Remote Desktop it sits at the logon screen for 10-20 seconds before logging me in. Once logged in I found the following three errors in the Windows System Event log, all logged as Event ID 7011 with the source Service Control Manager:
The Smart Card Device Enumeration Service service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion.
A timeout (30000 milliseconds) was reached while waiting for a transaction response from the ScDeviceEnum service.
A timeout (30000 milliseconds) was reached while waiting for a transaction response from the UmRdpService service.
