Continuous Account Lockout on RMIT computers

Every week when I come into lab classes and try to log into the rmit computer's I get this message:
"The reference account is currently locked out and may not be logged on to."
Each week I call the help desk and they tell me that the account isn't locked and that I should be able to log on. Im able to log on after that but the issue persists the next week.
If there is a solution to this problem I am not aware of then please let me know.
Thank you
