We recently upgraded our client PCs to Windows 10 and had sorted out a majority of the issues. This week we found that several of our users no longer had their mapped drives appearing in explorer. We push our drive mappings via GPO from our Windows 2012 R2 Server.
When logged into one of the problem clients with an administrator account and run net use it comes up showing no drive mappings. I am able to browse to the network locations using the UNC path. I attempted to create the drive map manually using net use and get the following error, regardless of what drive letter I attempt.
net use Z: \\server\path
System error 1920 has occurred.
The file cannot be accessed by the system.
On top of this, when I run GPRESULT I receive the following:
The following GPOs were not applied because they were filtered out
-------------------------------------------------------------------
Network Drive Mapping
Filtering: Not Applied (Unknown Reason)
So it appears I may have two issues 1) I cannot map network drives manually and 2) the GPO isn't being applied, unless #1 is causing #2. The only way I could get the drive to map was to right click on the network location and map the drive through the Windows 10 GUI.
After some web research I did try adding this reg key to the client with no success:
"EnableLinkedConnections".
Any suggestions? We have not changed anything this past week in our network config. Was this caused by a MS update?
