Corrupt TranscodedWallpaper File after deployed wallpaper via GPO

Hi all,

I have some pcs got black screen after I have deployed wallpaper GPO .

This is my GPO :



And there is my script :
98827-1.png98832-2.png98828-3.png98833-4.png98834-5.png


Almost Clients applied GPO and showed correct wallpaper image .

But, some PCs have got the black screen .

I checked on the PC which got the black screen , GPO has applied . every thing look like normal .

After google, I found that the Wallpaper corrupted. The TranscodedWallpaper has 0 KB size .

Then I need delete all folder and files after Themes :

After that, I run Gpupdate /force again. The windows already applied wallpaper .

I don't know the root cause .

Hope that someone can give me advice to resolve my issue .

Sorry my English is not good.

Cheers,

Hi,

@HanhTrinh-2473 I can't promise 100% but I believe computer GPOs are still inheritated via User VPN, and they might do part of the job, but they will not perform some activities which are required during start process. So if you are lucky, those computer GPOs still might work.

Hello @HanhTrinh-2473,

Thank you for posting here.

1.Does the user van.ho apply all the GPO settings you mentioned above?

2.If so, why the date modified of wallpaper is 1/31/2021 (three months ago )?

99131-file1.png

3.Is the file successfully copied to the specified path?

4.If the file is successfully copied to the specified path, is the copied file normal?

From the date modified, it seems the issue (The TranscodedWallpaper has 0 KB size) is not caused by wallpaper GPO.


Based on your description: Then I need delete all folder and files after Themes.
After that, I run Gpupdate /force again. The windows already applied wallpaper.

I suggest you can push a script to delete all folder and files in Themes for all users.
After that, the windows will apply wallpaper.


Hope the information above is helpful.

Should you have any question or concern, please feel free to let us know.


Best Regards,
Daisy Zhou

Hello ,
"delete all folder and files in Themes for all users" I think there is a good idea.
All pc I checked, the files and folder already copied exactly.
But I really want to know why the pc get black screen ( cached theme ).
Do you have any advice?

Just to jump in on this one (even though an answer is provided). I saw this at a client site with an almost identical situation (we used GPP's to copy the updated wallpapers locally that the GPO points to as the wallpaper). We found that if we renamed "TranscodedWallpaper" to "TranscodedWallpaper_OLD" (effectively a delete of the file), when the user logged out and back in, the file got correctly recreated and the issue was resolved.
