I have a VPS running Windows Web Server 2008 R2. I'm able to connect using Remote Desktop from my home PC (Windows 7), personal laptop (Windows 7), and work laptop (Windows XP).
However, I cannot connect from my work PC (Windows 7). I receive the error "The logon attempt failed" in the RDP client, and the server event log shows "An account failed to log on" with this explanation:

I can connect from the offending work PC if I start up Windows XP Mode and use the RDP client inside that.
The server is part of a domain but my account is local, so I'm logging in using a username of the form hostname\username. None of the clients are part of a domain. The server uses a self-signed certificate, and connecting from home I get a warning about that, but connecting from work I just get the logon error.
