Windows 7 RDP Com Port Redirection not working

[KevinJK]

I am trying to redirect com port from Windows 7 to Windows 7 over RDP but it never works.

I can redirect Drives, printers and everything else, just not com ports.

Any ideas?

Thanks

Redirecting COM ports over RDP in Windows can sometimes be tricky due to various settings and configurations. Here are some steps you can take to troubleshoot and potentially resolve the issue: 1. Group Policy Settings: - Ensure that the Group Policy settings on both the client and the server allow for COM port redirection over RDP. - On the client side, check the Group Policy settings under Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Connection Client -> RemoteFX USB Device Redirection. Ensure that the policy "Allow RDP redirection of other supported RemoteFX USB devices from this computer" is enabled. - On the server side, check the Group Policy settings under Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Device and Resource Redirection. Make sure that the policy "Do not allow COM port redirection" is not enabled. 2. COM Port Mapping: - Ensure that the COM port you want to redirect is available and not already in use. You can check this in Device Manager on both the client and server machines. 3. RDP Client Settings: - When connecting to the RDP session, ensure that the "Ports" tab in the RDP client settings has the COM ports you want to redirect checked. 4. Network Connection: - Check the network connection between the client and server. Sometimes network issues can prevent proper COM port redirection. 5. Driver Support: - Make sure that the drivers for the COM port device are correctly installed on both the client and server machines. 6. Update RDP Client and Server: - Ensure that both the RDP client and server are updated to the latest versions to benefit from any bug fixes or improvements related to COM port redirection. If after checking these steps the issue persists, you may also consider checking event logs on both machines for any error messages related to COM port redirection. These logs can provide more specific details on what might be causing the problem. If you continue to experience difficulties, feel free to provide more details, and we can further troubleshoot to identify the root cause of the issue.
