We have a few computers in our company (2 or 3 at the most) that will drop RDP login credentials after a full reboot. After turning on 'Allow me to save my credentials', the computer will keep them saved until it is rebooted. Logging out does not drop the credentials. The computers all have SP3, and thus, the newer RDP 6.0. Since there are only a few computers with this problem, and not much online about the issue, I'm guessing it is computer specific. The problem is very consistent, though. Any help would be greatly appreciated!
I also looked into uninstalling the client from the NTUninstallKB925876 folder like some suggestions I've read but that folder isn't there.
