Things that make the network engineer in me go hmmmm....
Looks like you are signed in through a https:\\ portal page, but that could be Apache just giving to much info.
What browser are you using? Internet Exploder? FireFox? Safari?
Both IE and Firefox seem to be normal. Although telling the techs exactly what the page address you were on before the Error 404 happend would probably help them a great deal, because I'll bet money that whatever icon or link you clicked on refers to a physical document in a location that has been moved. Along with the Error Handle document too it would seem.
Gotta love comupters.
