Question : Execute Script On Shutdown BEFORE network connections close

I have a script I want to run at shutdown that copies a select few (important) employee's .pst(s) to a mapped "drive" on the network.  

This is being in lieu of an exchange server to have a tape backup of their very important e-mail.  

The problem is when I run a script from the group policy "on shutdown" the network connections close before scripts are run.

Any ideas on how to run this script on a shutdown event but before network connections close?

Answer : Execute Script On Shutdown BEFORE network connections close

The way that policy works (I use it to disconnect drives amongst other things), I don't think so.

So if I were faced with this, I think what I would do is put a line in the script in front of the copy to map the specific drive, and then a line after the copy to disconnect the same drive.
