Hi!
Are you unable to map the NAS, or can you not even access it?
Are the other computers also running Windows 11? Check if they all have the same build.
- Press WINDOWS + R > Type "winver" (without quotes) > Take a screenshot of the window and send it to me.
How do you access and map your NAS? Do you use a password for access, or a guest account?
What specific error or message appears?
