I need to backup users .pst files. The current method I am trying is making a shadow copy using Diskshadow. My script works great all but Diskshadow needs to be ran as administrator but also needs to retain the logged-on user's environment variables; specifically, the %USERNAME% and %HOMESHARE% variables so the right user’s files get copied up to the right network location. I have for the most part got this to work), but there’s no straightforward (or secure, at least) way to pass the password. If I set up a scheduled task to run the script as a domain user with local admin privs, the environment variables get lost. I need to run this script automagically so that there should be no user interaction.

If I could figure out how to make a scheduled task run as another user but keep the current user’s environment, I think this would work, but I’ve been beating my head against that for a while now, without any luck.
