Along that line of thought, as a test, consider using "use first available" rather than a static drive letter to ensure that there are no conflicts.
If gpresult is showing that this should apply (which I believe you indicated it is), you may also want to consider enabling detailed logging on the GPP Drive Mapping policy to see if that reveals anything useful: http://blogs.technet.com/b/askds/archive/2008/07/18/enabling-group-policy-preferences-debug-logging-using-the-rsat.aspx It's been a while since I've had to do this, but I recall it helped me out a few years ago while troubleshooting something with GPPs. -Aakash Shah From: [email protected] [mailto:[email protected]] On Behalf Of J- P Sent: Tuesday, March 31, 2015 6:44 PM To: NT Subject: RE: [NTSysADM] RE: mapped drives GPO Is the hardware identical on all machines, are there perhaps other drives (usb,card reader, etc..) using the same drive letter? does disk mgmt show anything , can you try changing he drive letter on the script?

Also, I assume that you can manually connect when logged in as the user?
