Hi there,
i'm a cs undergrad with a background in programming, and started doing
some admin scripting in windows using wmi. I encountered this _really_
strange problem recently.
I have domain admin access on Active Directory, and was able to pull
some info on printers off of some computers using wmi, by getting the
SWbemService object using the ConnectServer method of the SWbemLocator
object, with explicit credentials.
Then I installed a scanner on one of the computers and installed the
drivers from the manufacturer. I restarted the computer, then tried to
pull info from wmi again, with the same script code and credentials.
Alas, it didn't work this time and i got a 'Access is Denied' from the
SWbemLocator object.
This happened to two computers before I suspected the scanner utility
installation was the problem, and confirmed this on a third computer. I
tried uninstalling the software and running the script again, but it
still wont authenticate me, even with Administrator on the local
computer.
Another thing i noticed while trying to diagnose the problem: looking
at the 'dependencies' tab in the Administrative Tools ->Services comes
up with the 'Win32: Access is Denied' error, which i assume stems from
the same problem.
This is really inexplicable to me; i have absolutely no idea how a
scanner installation, or any other software installation for the
matter, might affect authentication on active directory. Does anyone
have any idea at all??? Thanks in advance!
cheers,
ben
