Install pstools on your computer/server

Create a script

usage: du [-c] [-l <levels> | -n | -v] [-u] [-q] <directory>
   -c     Print output as CSV.
   -l     Specify subdirectory depth of information (default is all levels).
   -n     Do not recurse.
   -q     Quiet (no banner).
   -u     Count each instance of a hardlinked file.
   -v     Show size (in KB) of intermediate directories.


You can add each server in the script pipe the output to a file and then have a report

schedule it in task manager and run it on a regular basis

If you can email via batch then you can also email the report to you.
I use febooti command line smtp email works great

Need help with script let me know.
