Hello,
Thank you for posting in Q&A forum.
Please kindly try login as domain administrator and change the file owner again? As sometimes it chould be controlled by group policy setting and not able to be adjusted via local user account.
Meanwhile, you can open CMD window and run command:
gpresult /h c:\temp\gp.html
to collect and export gpo setting for further check.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards,
Jill Zhou
