Hi, Thank you so much, i was trying many things and i found out it was a problem with the user that runs the SIA service, initially it was with LocalSystem, and it was failing, after that i tried with the local Administrator, but also had the same problem, after some reading i did notice that there was a Domain administrator, so i tryed with it and it works perfectly. Also i found something about the Auditing difolder, it has more than 13K files, so i moved them to other disk and it worked, SIA started well.
Thank you all for your help.
