I'm just trying to find what takes precedence in loading a GPO.
Specifically, will drives map prior to scripts running?
I have an .exe in a network share that I'm running every time a user logs in, and I dont know if I should load it via the mapped drive or through the network path.
The order by which Group policy client extensions are processed is a fixed order.
You can see which order by checking the following registry key:
Within the same GPO, it's a little bit of black magic. What you can do is create two separate GPOs for each action and use precedence to order them in the way that you want them executed.
That said, you should really probably just use the UNC and take the drive mapping out of the equation.

GPO is applied prior to scripts being run. However it is still unclear about the precedence when the script is being called via the GPO...
