For those of you using DiscBuilder, there is a bug in the latest driver update pack. While the nVidia driver set I included claimed to have fixed the remote desktop host crash, it does not. Thus, if you build a disc using the latest updates, you will not be able to use remote desktop to connect TO that computer. Outgoing connections still work. And unlike the earlier driver sets that just prevented RDP from connecting, this version actually crashes the host when you try.
I have located a set of fully working drivers that also include PhysX support, and I am working on integrating them now. I'll patch the update files as soon as I have everything formatted properly. (it takes awhile)
I'll update this thread when the new update is live. (updates are installed automatically each time you run DiscBuilder.)
