Powershell – Rename domain computer remotely (within an active directory domain as well)

I wanted to rename a couple of computers within our active directory. After some research i figured out thats it seems to be nearly impossible to rename a computer by just touching one object: the ad computer object, or the computer (client) itself. My first thought was „ok, you have to rename both objects, rejoin the computer and hope everything works“. But that’s no solution, that makes me happy, because the more steps you do, the more problems can occure. For examples, what happens if the computer has to reboot, after renaming to get correct rejoined? Do i have to create a local admin account at the clientside to have permissions after the computer lost his connection to ad? And so on… I played around, renamed the ad object, rebooted it – negative, the computer has to be joined again. After that i tried it the „bottom up“ way by renaming the computer by hand, and rebooted it instantly. While the computer was shutting down i noticed, that the computerobject in active directory was renamed before the computer was finished with its shutdown process. So i tried this several times and every time the ad computerobject was renamed properly. YAY!…
