DBCC Failures

Hi. I am running SQL2000 standard edition on a Windows 2K server. I have this annoying problem that the jobs I create through the maintenance plan wizard fail consistantly on a certain database that has one table in it. Just the database integrity check and update statistics part of the maintenence plan fail, the backups are fine.
This will occur on a brand new database, with the default options selected and with only one empty table in it. The script to create the table and indexes is below. The errors I get from the maintenance plan are:

--Check Data and Index Linkage
[Microsoft][ODBC SQL Server Driver][SQL Server]DBCC failed because the following SET options have incorrect settings: 'QUOTED_IDENTIFIER, ARITHABORT'.

--Update QP Statistics
[Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 1934: [Microsoft][ODBC SQL Server Driver][SQL Server]UPDATE STATISTICS failed because the following SET options have incorrect settings: 'QUOTED_IDENTIFIER, ARITHABORT'.

I have messed around with setting these db options on and off with no effect on the success of the maintainence plan. I am wondering if anyone can replicate the problem on there own installation or have any thoughts on how to fix. Oh if I take the formula off of the table the jobs run successfully.
Thanks in advance.
