RDPDD.dll failed to load - Remote Desktop woes

I've spent most of today without RDP access to my server. As soon as I connected I got immediately booted off, from any machine. A telnet connection to port 3389 connected fine, which led me to believe something was playing up on the server.

The day before, I had updated my Nvidia graphics drivers, but this couldn't cause RDP to fail, surely? Yes it can!

I saw in my system logs a large number of 'information' errors saying "Application popup: : SystemRootSystem32RDPDD.dll failed to load". A Google search for RDPDD.dll led me to my solution via Brad Rutkowski's Blog and the Nvidia Forums to add the following registry key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

"SessionImageSize"=dword:00000020

This worked a treat, and I can now continue to be lazy :D
