Not sure if this will help anyone but this is the recap of my testing of Hybrid device renaming:
- Logging as local admin and manually changing the name of the machine: It works
- Remotely using Rename-Computer powershell command, works.
Both actions above see the change of name reflected in Endpoint Manager. If joined by Autopilot, only the Hybrid object changes name, the Autopilot (duplicate?) AD joined object stays the same, although I haven't found any issues.
- Rename Device in Endpoint Manager. Does not work. Worse, it breaks DC trust for all user's devices. I haven't found a way to recover this apart from resetting and reenrolling.
- User changing name in Company Portal: Nothing happens. All the AD and AAD names stay the same. It seems to just update the "Display name" for the user.
Can anyone else replicate the above?
