how ntrights.exe just saved colleague from hide

my colleague denied local logon to group “everyone” on one of our users PC and restarted ……. realized what
trouble he was in. neither local user nor domain user can login from console. It
gives an error

“local policy of the system does not allow you to login

finally i could solve it by ntrights.exe

ntrights -m \\<machine ip> -u everyone -r SeDenyInteractivelogonRight

wonderful tool………. but no password is

a miscreant can use this to cause chaos in a network.
