How do I find out what's causing an access denied error?

Question

I am getting an access denied error when I try to run a vbs script that uses WMI to do some stuff to IIS on Windows 7. Is there some sort of tool that can tell me what's causing the access denied?

Answer 1

Not 100% sure if it will work, but you could always try one of my favorite SysInternals tools called procmon (Process Monitor)

Usually in strange permissions issues, I would run procmon, then launch/run whatever app is having issues. There are a lot of cool filtering techinques within ProcMon that should help you go through all of the results. Look in the "Results" column for things like Access Denied, etc...
