hxxp://download.microsoft.com/download/b/d/c/bdccea1b-96d9-4ad9-8045-56619af95835/qtr40enud3.img can't be found, but one and two can, anyone know what is going on?

i guess it depends on which akamai box you hit

works for me:
C:\>wget -O nul download.microsoft.com/download/b/d/c/bdccea1b-96d9-4ad9-8045-56619af95835/qtr40enud3.img

=> `nul'

Thanks for clearing that up, it was just a bit worrying since I downloaded 1 and 2 with no problem, try 3 and hit a problem, just a coincidence though.
