Permissions of existing user may not allow them to log in, or `NTUSER.DAT` may be missing. This will usually create a new folder in `C:\Users` named like `<username>.<domain>`, for example `myuser123.DOMAIN`. Observed outcome is user missing files in their user profile, which is very confusing for end users. This can stack if it happens again, creating more user folders.

Most easily solved by either resetting permission inheritance on user folder, or deleting via `sysdm.cpl` after copying any important files out.
