Possible Major Issue with Windows 11 22H2

I attempted to clean install Windows 11 22H2 on my work laptop as a weekend project. Everything seemed to be working well, until I tried to add my user as a local admin. I kept getting a username or password is incorrect for my domain admin creds. I was able to RDP into a domain controller to verify I wasn't locked out. Tried hitting multiple file shares, no dice. I was prompted for user creds. My older Surface was recently upgraded, so I verified the same failures on that as well.

All told, three 22H2 laptops seem to have a major issue with domain authentications. The Surface was upgraded, so I was able to roll back to 21H2, and all of the issues were resolved.

Has anyone encountered this yet?

I don't run Win 11, but you might find this Askwoody.com article helpful. The video linked in the article may also be helpful. Hope this helps.

+1 for something with Credential Guard.
