RDP missing from Pocketcloud

RDP missing from Pocketcloud

I have installed the Pocketcloud companion software on a new Windows 7 Pro PC which is running on our corporate network.

In the PocketCloud companion software it says RDP is listening on port 3389, and VNC is listening on port 5900.

However on my Android device only the VNC connection has been automatically discovered. Why hasn't the RDP been automatically discovered?

I've installed Pocketcloud companion software on other WinXP PCs in the same network and both VNC and RDP are successfully discovered. Its just this new Windows 7 machine which is giving me trouble.

Any help appreciated.
