Oracle Database Discussions

I am using Oracle 10g R2 on Windows 2003. I just put up a new database and the system account keeps locking. I unlock the account, but it will lock again sometimes as often as every 15 minutes, at other times it will be as long as an hour. The system account is assigned to the Default profile and per Oracle's suggestion I set everything in the Default Profile to unlimited, but this didn't help. Anyone have any ideas?

SQL> select profile from dba_users where username = 'SYSTEM';

PROFILE
------------
DEFAULT

SQL> select resource_name, limit from dba_profiles where profile = 'DEFAULT';
