Enabling Redirection of Pnp Devices on Windows 2008
When I connect each day from my XP workstation to our Windows 2008 servers via Terminal Services, I generate an Event ID 36 telling me that "Redirection of additional supported devices is disabled by policy." Description of how to address this warning (which can simply be ignored) is at:
http://technet.microsoft.com/en-us/library/cc775202.aspx
That said, since I hate ignoring warnings even when they are innocuous:
- What PnP device does the server think I am trying to redirect? In the remote desktop connection settings, the only item checked under "Local devices and resources" is Clipboard (I've gone into "More" and made sure everything is unchecked including Smart Cards). I've also got nothing hooked up to my mobo other than a graphics card, mouse, & keyboard.
- Is there a security risk or other issue with enabling the redirection of Pnp devices as the article outlines?
Thanks!

Thanks pcbonez - I'm with you about the warning coming up because of PnP devices on the client PC. Not sure what was being registered because the PC was barebones - nothing connected to the motherboard other than a basic graphics card, USB keyboard, and USB mouse.
Aside from that, and perhaps more importantly, do you know if I would be creating a security vulnerability by enabling client PC PnP devices to redirect to the host server?

Thanks pcbonez... I'm decided to try enabling PnP device pass-through on a test server. The odd thing is that none of the restrictions listed in the link I originally posted are enabled (i.e. PnP devices should be enabled according to the TechNet article).
Has anybody else encountered this warning message on a Windows 2008 server and been able to resolve it?

That didn't work for me, however, changing the "Allow RDP redirection of other supported RemoteFX USB Devices from this computer" to enabled in group policy seemed to do the trick. (Computer Config-Administrative Templates-Windows Components-Remote Desktop Services-RemoteFX USB Device Redirection)

When a user establishes a remote session with a Windows Server 2008 terminal server, the supported Plug and Play device attached to the user's local computer can be redirected and made available to the user in the remote session.

What that's saying is the problem device in not in the Server but in the user's local computer (the client PC).
The PnP info for some device in the client PC is being sent to the server and then being redirected back to the client PC [but now 'inside' the remote session] so that device can be used locally while the user is in the session with the server.
