> Maybe your work finally blocked port 3389.

I work for a small company and we're all open about this sort of thing. They
know I use remote desktop and they'd tell me if they intended to block the
port.

I did have to forward port 80 from my router to my home machine when I set
up IIS but I'm convinced I didn't 'unforward' the RDP port in the process. I
really can't think of anything else that may have changed!
