Some drives not mapping by GPO in win 7 clients with Win Server 2012 Essentials

On setting up the server, successfully added 2 mapped drives. Now want to add 2 more but the process is not working this time. Can any one assist?

Extra drives will not map on desktops or on server even.

Example error message for each of the 4 drives (including the original 2): The user 'M:' preference item in the 'Default Domain Policy {31B2F340-016D-11D2-945F-00C04FB984F9}' Group Policy Object did not apply because it failed with error code '0x800708ca This network connection does not exist.' This error was suppressed.

As per error it seems path of network  map drive is not accessible or hostname of shared server is not getting resolved.

Try to connect without GPO
open Run from Start Menu (Start+R)
then type \\servername.mydomain.local\sharename
Newer desktops use quite a few drive letters for USB ports - typically these are hidden from explorer until a drive is connected.  You may want to check disk manager to make sure you aren't trying to push a mapped drive to a drive letter that is already consumed by other resources.

Maybe you can use Group Policy to Map drive. Steps are explained in this article.

Ref above Comments:
I am already using Group Policy for the Mapping.
As I am using drive letters like M and Q, these are not in use by other resources.

Amit: The path is accessible, as it is actually the server that is generating this error.
When I tried typing \\servername.mydomain.local\sharename , it worked without any problem.

From the client box try accessing \\Domainname\SysVol and then browse the nested folders {31B2F340-016D-11D2-945F-00C04FB984F9}.

In addition to that run the command "gpresult /v" on the client box and paste the content here.

See attached some screen shots. used group policy to map drives. Have tried various settings like replace, create, update, etc, but no further forward. Thanks for help.
Rakesh KapoorCommented:
Change the action to Create and select the option "Show this drive" and "Show all drives".  Try not to give space in Share Name. Out of these mapped drive which drive is working and which is not working ??
