I think an error has been introduced into my XP Pro SAM file, it seems one user is assigned to a group that doesn't exist. It prevents the user from logging on, and I can't even edit the user's groups through the "Computer Management" tool. It gives this error:
"The following error occured while attempting to read the properties for the user XXX: The group name could not be found."
Anyone have any ideas about how I could reset the groups the user belongs to without going through the "Computer Management" tool? Changing a user from "administrator" to "limited" in the "Users" Control Panel does not help. Does the registry hold any of this information? Is there a third-party tool I could try?
