How do you unlock a computer

Hello,
I work in a school and all the children log in as pupil without a password.My problem is they cannot get in to 2 of the computers .It says "the trust relationship between this work station and the primary domain failed".I have a feeling that the children have pressed something they souldn't.

Talk to the IT department. Those 2 computers have lost their domain membership.
