After performing a Bare Metal restore with Veeam for a 2012 R2 server OS you may find logging in remotely via Remote Desktop taking longer than usual.  You may experience a delay at the logon screen for about 10-20 seconds before logging in and the following three errors may be found in the Windows System Event log, all logged as Event ID 7011 with the source Service Control Manager:

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the UmRdpService service.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the ScDeviceEnum service.

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.

The reason for this is the RDP service is attempting to use Smart Cards for authentication when a client attempts to connect.   It seems that the Windows Server OS enables the Smart Card service after a restore to new hardware (partial OOBE). To fix this, change the Startup Type of the the Smart Card Device Enumeration Service from Manual (Trigger Start) to Disabled.  After doing so the unwanted delay on remote logon will be resolved.
