"I can only get this to work if I disable UAC on the Windows 7 client. Is this expected?" "This should only happen with administrative user accounts. The drive mapping occurs in an elevated user process. The Windows Explorer process is a non-elevated process. Mapped drives, regardless of how they are mapped, by default do not span across processes of different elevation. Normal User accounts should not have this problem. You can bypass the problem by mapping the drive as a scheduled task, which would occur under the non-elevated process. Or, you can enable the registry setting in MSKB Article ID: 937624."

That's was it. Thank you!! On Sun, Nov 20, 2016 at 9:11 AM, Eric Wittersheim <[email protected]<mailto:[email protected]>> wrote: Are the users local admins? UAC can block mapped drives when the users are administrators. You can check this by opening up a cmd prompt and switch to the mapped drive letter. This shows the gpo is working but it's mapping the drive for Administrator instead of the intended user.

In it, we have a mapped drive which isn't work. Looking at GPResult shows the policy being applied. Using NET USE, we can map the drive with a user logged in. We have unchecked, reconnect at logon and it still doesn't work. The drive map action is Create. We also tried Update. The GPO does work because other elements- a message on the logon screen is displayed. The DC is a Windows 2012 R2 server and the workstation is a Windows 10 Pro version. It also is not working on a Windows 2012 R2 terminal server. Any help would be appreciated.
