New entry in the unbelievably-misleading error message category: Windows 7 x64 RDP Client

I spent quite a while earlier trying to make an RDP connection to another system on my network. The error message from the RDP client was:

Your computer could not connect to another console session on the remote computer because you already have another console connection in progress.

You can imagine the range of things I tried to resolve the issue.

The actual issue? The machine had a new IP address and I was trying to connect to its old IP address. Great error message :-(

sigh
