Active Directory - WallPaper Assign to All the AD users

I have created group policy and link to the it department . but wallpaper is not applying . Any reason for that   .rsop.msc  indicating my new setting on the result but physically not visible when I Login to the domain

my client PC is running windows 8.1 and server 20018 r2 . I have applied the wallpaper and but not working with the client . Any idea ? need any hotfix to installed ?

\\server\Shares\Wallpapers  (Allow Read Access for all Users)

I have done every thing except all users . I have given authenticated users as read . Do I have to give access to Domain\users as well . Anyway I can access the set path from the client machine . but still client PC will load with the black background . when I check with the client PC , I can see the  set wallpaper in the local client pc under personalized wallpapers section  .     I have applied that manually and restart the client PC . then it will go back to the old blank black background

I will try this too . but issue is all the users in that OU and no one get that wallpaper
we have  windows 7 /8 /10 users in that  OU

The "Desktop Wallpaper" Group Policy setting is not applied in Windows 7 or in Windows Server 2008 R2

Article only for windows 7 and server 2008 R2

I have 6 users in the above  OU and 3 of the users getting my new wallpaper . Including my PC not getting that wallpaper  . Any reason for that ?

I have realized some big issue with applying new   policy setting will take longer generally

windows 10 pcs only same OU and both Pcs not getting new GPO based Desktop wall paper . my PC running windiows 8.1 and can see the RSOP result as newly assign path  . But it didn't appear on the PC

add read rights for domain\users in NTFS Permissions on that folder too

I have given read and execute / list folder content and read permission

Still the same

have you tried to access the location in server in which .jpg exist ?
\\server\Shares\Wallpapers

the DC administrator and all domain users should have access to that location

try to access that location from DC and from the client as well

Both the location can access path . Do you thing this due to any service Pack Issue  . thing is windows 8.1 PCs also getting this problem .

permission and RSOP as the same in my case too

what is the best way to deploy  the wallpaper for following requirement wise

different wallpaper  for each define UO -I have create separate GPO and link to each respective OU ?

Same wallpaper for all the users in the domain -  create one GPO and link to all the OUs ?  or Can I change the default GPO : please advice me on this .

How to disable the link GPO from the OU level - un tick the  "Link Enable "

The computer that are not getting the wallpaper will work  , when I log in to the computer new domain user . I have tested that on the few pcs that are label as not working ,  now it is working with that way  . How can we resolve that issue  ?  is there any way we can update the local PC caching Issue
