How can I get a Powershell script which maps network drives to execute at logon to any workstation in my domain

Question

I want to map network drives for each user when they logon to any workstation in the network.  I have created and tested the PS1 script which works fine where the drives attach and used persistent parameter.  I have updated the Windows 7 Professional
64-bit workstation to the latest PS 4.0 code.  I have created the GPO and believe everything is assigned properly.  I made changes to allow execution of local and remote signed scripts.  I have forced the changes on a workstation using GPUPDATE
/force, but the drives do not connect.  The GPRESULT is as follows which shows the policies are in place as shown below.  
What am I missing to get the script to execute?

First: Only one of all current answers points in the right direction.
You picked the local sysvol path on the DC which does not exist on
clients, of course...
The Path to the script MUST be an UNC path starting like
\\mrc.net\sysvol\mrc.net\Policies\...
Second: You CANNOT execute PS1 directly (unless you change the .ps1 file
extension configuration). The "Name" MUST be "powershell.exe", and the
script itself goes into "Parameters".

NO THEY ARE NOT EVIL, if you know what you are doing:
Good or bad GPOs?
