I have a workstation trying to map the COM ports to the RD session which is hosted on a Hyper-V 2012 R2 as virtual machine (GEN2). No matter what I do, the port doesn´t appear in the device manager. Group policy is configured to always allow COM/LPT ports redirection. The server and workstation is temporarily connected on the same network. COM port on the workstation is not emulated in any way. On the workstation the COM port is labeled as COM9, initially tried with the COM1. No errors in the event log.
Any ideas what´s wrong?
