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..
(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.
If this is the problem I've been experiencing (for years, at this point), here are some additional data points:
There are two workarounds:
I really hope MS takes this bug seriously some day and fixes it. Until then, we've got the workarounds listed above.
