logman.exe throws an error "Administrator refused request" in factory mode

Hi ,

My apologies if I have chosen an incorrect forum to post this . I did not find a suittable forum to post my question.
In Windows 8, I'm using a script to create the perfmon counters dynamically in factory mode using logman.exe.

The creation of the counters is successful but when the script tries to start the counters, it fails with an error :

"Administrator refused request"

tried by running the script in a command prompt with "Run as Administrator" but no success :(

Obsevations:

The same script works without any issues in normal mode (out of factory mode). 

The same script works fine without any issues in factory and normal mode in Win7



Any help in this regard is helpful.

Thanks
