You would have got your Exchange into one big pickle if you uninstaled
IIS and then reinstalled it. What procedure did you follow and who
offered that advice (if anyone)?
When you did the reinstall, did you select the asp.net as additional
components?

I don't remember where i have found the information but i'm sure that is was
one Microsoft KB, i have reinstalled als asp.net components, i have tried to
resolve the problem following differents ways, the first time that i ahve
tried to use oma i have obtained the precedent error, then (with another pc)
i have created a new server installation ad at first time all worked fine, i
have installed sp1 of exch and all was ok, i have disintalled IIS and
reistalled it, i have stooped exchange and when i have restarted exch the
problem has been introduced, after this moment I am not successful to remove
the problem.
I will hope that you understand me, i have some problem with my english
Thanks Emanuele
