RDP client is connecting to the server just fine, but only drawing about half of the login screen and then stopping. This is happening on two of my Windows 7 Ultimate boxes, both of which are clean installs. I have three other Windows 7 Ultimate machines that are able to connect just fine, all of these are also clean installs. The only differences that I can find in the setups of the machines is that the ones that don't work properly have multi-core processors and have hardware virtualization support turned on (for XP Mode support in Win 7). I'm using a D-Link WBR-1310 router and having the same issue in both wired and wireless setups. Any help would be awesome. I may even dance.

Lots of variables here..

  • Does it happen if you use a crossover ethernet cable to directly connect the two machines, ruling out the existing switch/router and cabling?

  • Are there other differences is hardware configuration between the machines? Like video card, ethernet card, etc?

  • Have you tried updating the ethernet drivers? Windows 7 drivers are pretty up to date out of the box because the OS is so new, but I've seen really surprising problems from default windows ethernet drivers before.

  • Have you tried updating the video drivers? Those are always worth updating because they change so rapidly.

(You could also try using RDP from within a Windows XP VM on the same machine, just for kicks.)

I highly, highly doubt this is because the relevant machines are multi-core. I'd personally go on a driver-updating frenzy myself, based on previous experience.

Previous experiences like this perhaps? :) blog.stackoverflow.com/2009/02/server-speed-tests –  John T Jan 13 '10 at 4:37
    
I gave it a shot, and new network drivers didn't seem to solve the problem. I upgraded the wired NIC drivers on my desktop and laptop, as well as the wireless drivers on the laptop. Still having the same issue. –  Scott Wolf Jan 19 '10 at 14:14
    
@scott did you try RDP'ing from the XP VM on the same machine? –  Jeff Atwood Jan 19 '10 at 14:15
    
Seems to be working from the XP VM. Odd. –  Scott Wolf Jan 20 '10 at 4:56
