Network drive map through GPO not working on Windows 2012 (Neither via logon script nor drive maps)

Although I thought this would be easy I am unable to automatically connect to a network drive via GPO.

I tried through a batch file on (User Configuration / Policies / Windows Settings / Script / Logon) which I made sure to browse via NETLOGON share.

File Content:

net use z: \\\Shares\DMS

A finally I also used the Drive Maps (User Configuration / Preferences / Windows Settings / Drive Maps) with following parameters:
Action: Replace - Location: \Shares\DMS - Reconnected: Checked - Use: Z: - Hide/Show this drive: Show this drive - Hide / Show all drives: Show all drives.

By reading some tips in the Internet I also disabled the fast logon.

Just to make sure, I tested the batch file and the NETLOGON share in a target laptop, and everything worked fine.

This is the gpresult /z for a target laptop:

Logon Scripts

GPO: Default Domain Policy
    Name:         \\PM01-W12-DCO\netlogon\logon.bat
    Parameters:
    LastExecuted: This script has not yet been run.

I just ran into this issue on a Windows 10 laptop and learned that it's a known issue with Windows 8/10 and Server 2012.

If the reconnect option is checked in the drive map, it will just fail, no errors or issues in event viewer that I could see. As soon as I unchecked the reconnect option, replicated changes and then ran gpupdate /force on the Win 10 laptop in question the drive mapped without issue.

Given that you've tried two techniques without success, I'd say this is almost certainly going to come down to a permissions issue.

Go back to using Group Policy Preferences - you can then review the event log to see why they're failing.

Edit: Please don't use the Default Domain Policy for this stuff, if you break it you'll be stuffed. Create a new GPO and link it as appropriate.
