Renaming folders or files

I have been facing this issue from time to time (like once in 2-3 months). When I copy a file from one file to another and if I want to rename it, it’s not allowing me to change my file name and its prompting that the desktop admin must give permission. It’s not required for my PC in the first place. And even if I give permission it’s still not changing and its showing as I am not allowed to change. Has this issue happened to anyone? If yes, please let me know how it can be rectified.?
