I wanted to setup Remote Desktop Web Connection on my home server so I could log-in to it from machines that are either behind firewalls/proxies or just don't allow the Remote Desktop Client to run. I did the right thing, searched for a good article, found one on Microsoft's web site and followed it all the way through (pretty simple and straightforward).

Unfortunately, when I was trying to connect to my server I could see the main Remote Desktop Web Connection web page, but it was failing to connect with a Javascript error "Invalid procedure call or argument". The Javascript call affected was setting the resolution of the connection, which by default is "Full screen". Apparently that doesn't work very well with web connections, so using something more standard like 1024x768 was an easy fix.

Just thought I'd mention it to possibly save others some time.
