I cannot tell what's going on exactly, but a thing of sure is that I can't install MIT "and" SUS on the same server.
I tried to figure out why, how ... played some time in the IIS config, but nothing.
Ok I once installed MIT and then SUS, SUS was working perfectly, but MIT wasn't anymore.
I thought then I did something wrong with MIT, so I re-installed MIT and this went perfectly. But couples of weeks later, after some patches has been released, I found out no desktop were patched. Once more, after I played a while with it, I thought I did something wrong. At this time I was getting quite unsure about everything happened.
The exact bug with MIT is that I can't download the flash menu on the left side. (see the file, in french but still...)
The bug with SUS is that no client can't download patch from server.
(Since no one seems to know what is MIT : Microsoft Interactive Training. Which is a free software that came with our package of office XP)
