It may sound like a silly question but I'll ask it anyway? Are you sure that you are using SQL Server 2000? If so, this should not be happening and you may have a corruption problem of some sort. Everything in SQL Server 2000 is logged in one way or another and should not break the transaction log backup sequence.
