I tried logging into the domain a “few” times and I am now getting a message saying my account has been locked.

A user is allowed 5 attempts to login on to the Hansel domain. If you are not successful in one of those 5 attempts then your account will be locked for 5 minutes.  After the 5 minute lock out your account will be unlocked automatically and you can try logging on to the domain again.   If you try and log in before 5 minutes has passed your account will lock for another 5 minutes.
