GPO Drive Mapping not working

GPO Drive Mapping not working

Problem: 

I had an issue where I was fighting a GPO Drive Mapping Issue. I was beating my head against a wall, until I found a blog entry which indicating that a trailing slash can cause a drive map issue. 

Error: Group Policy Preferences Drive Mapping error 0x80070035 or 0x80070043

Environment: Windows 2012 R2 with Windows 10 clients

Fix for Windows Update
In the delegation tab of each gpo make sure that 'authenticated users have read permissions and also that 'domain computers' has read permissions too. this should put the gpo right again.

Ensure you use "gpupdate /force"

GPRESULTS /H and RSOP.MSC to diagnose the Group Policy objects and see if they are pulled down. Note: Preferences are often not shown in the list. 

Group Policy Preferences Drive Mapping error 0x80070035 or 0x80070043

Using group policy preferences to map network fails on workstations with error:
The user ‘%DRIVE_LETTER%’ preference item in the ‘%GROUP_POLICY_NAME% %GUID%’ Group Policy object did not apply because it failed with error code ‘0x80070035 The network path was not found.’ This error was suppressed.



or

The user ‘%DRIVE_LETTER%’ preference item in the ‘%GROUP_POLICY_NAME% %GUID%’ Group Policy object did not apply because it failed with error code ‘0x80070043 The network name cannot be found.’ This error was suppressed.



After double checking the path in the group policy in question, it turns out that the group policy preferences drive mapping doesn’t work if you put a trailing slash on the end of the path.  EG:
\\dc2010\qldfinance\ doesn’t work



however

\\dc2010\qldfinance does.
