Hello Dipto Adhikary,
Thank you for posting in Q&A forum.
Here are the answers for your references.
1.Why does this error occur, and how can it be resolved?
A1: How did you change wallpaper image?
Did you remove the old one and add a new one?
Or you change the name of wallpaper image?
If you put word or excel file into Netlogon folder, can you change it successfully or have the same error?
If you put wallpaper image into one new created shared folder, can you change it successfully or have the same error?
If you can change wallpaper image when in non-working time.
2.Could this issue have any impact on functionality?
A2: I think there is no impact on functionality.
3.What are the best practices for managing the Netlogon folder?
A3: Usually, I will put the wallpaper image into one new created shared folder.
Or put script file into the GPO GUID path, such as:
\a.com\SYSVOL\a.com\Policies{3339DBCC-97D1-4562-8808-8CC026DA343D}\Machine\Scripts\Shutdown
\a.com\SYSVOL\a.com\Policies{3339DBCC-97D1-4562-8808-8CC026DA343D}\Machine\Scripts\Startup
\a.com\SYSVOL\a.com\Policies{3339DBCC-97D1-4562-8808-8CC026DA343D}\User\Scripts\Logoff
\a.com\SYSVOL\a.com\Policies{3339DBCC-97D1-4562-8808-8CC026DA343D}\User\Scripts\Logon
I hope the information above is helpful.
