Hi,
The RDP connection is made from either of the workstations PC-A or PC-B (but NOT from PC-C)
On PC-D, open the firewall settings>set inbound rules "Remote Desktop - User Mode (TCP-In) & Remote Desktop - User Mode (UDP-In)">navigate to General tab>select Allow the connection if it is secure>navigate to Remote Computers tab>sellect Only allow connections from these computers>add PC-A and PC-B to the list
The RDP connection is made from either of the users USER-A and USER-B (but NOT from USER-C)
On PC-D, open Local Users and Groups>double click "Remote Desktop Users" group>add USER-A and USER-B to the list
Setting both of the above at the same time should restrict RDP connection to source machines and specific users simultaneously.
Thanks,
Eleven
