CC3 event log Failure Audit

[superaz300]

HI Guys,

In the event log I am getting the security error failure audit, and on the workstations, Teaching staff, students cannot logon, only system administrators can logon, if you logon to a workstation as a student user, it will not load and it appers as a security error in the event log with the students username,

 

Please help, I have no idea why it is doing this,

 

Thanks,
