If you want a successful restore of Exchange Server 2003, then avoid circular logging.  There is only one occasion to select circular logging, and emergency in which you are short of disk space.

Circular logging allows Exchange Server to overwrite transaction log files after the data that the log files contain has been committed to the database. However, if circular logging is enabled, you can recover Exchange Server data only up until the last full backup
So in effect circular logging makes sure that there are just 4-5 log files that keep overwriting each other and fresh set of log files do not get created.
