This script requires the Microsoft ArrayConvert libaries to be installed to function correctly. To download the ArrayConvert libaries visit Microsoft KB250344:

When downloaded extract the ArrayConvert files then copy and past all extracted files to the servers System32 directory:



Register the ADs.dll file using "regsvr32.exe ADs.dll" from the command prompt.



Navigate to the folder containing Bharat Suneja's script in command prompt and run the script using the cscript utility.
