Smart card service issue on Windows Server 2012r2 - terminal services (HyperV)

[erikhrast]

Hello...

I have virtualized terminal server on HyperV. All my remote clients use USB SC reader for certificate use.

Now pay attention... the Server 2012 has new feature regarding Smart Card use:

"Smart card reader detection logic has been added so that the Smart Card Service runs only when appropriate. On Windows Server 2012 and Windows 8, the Smart Card Service (scardsvr) automatically starts when the user connects a smart card reader and automatically stops when a user removes a smart card reader and no other smart card reader is connected to the computer. On startup, the Smart Card Service automatically starts if a reader was previously connected to the computer but a reader is not currently connected to the system. If no smart card readers are connected to the computer, the service will automatically shut down one minute after the last API call into the Smart Card Service. If a reader was never previously connected to the computer, the service will not start automatically."

And here is the main part... HyperV running OS doesn't support USB SC reader detection on remote client. When I insert the card nothing happens. The SmartCard service doesn't start (Automatic setting). RDP SmartCart share is enable on client.

If I start service manualy then the SmartCard is accessible. But only for the time of my login. if I logout then the service is stopped.

I also test it with logon to non HyperV server... the service starts with no problem.

For now I solved the issue with task net start SCardSvr on 1 minute.

Please can anybody help me with this...
