Question On QUOTED_IDENTIFIER

I have a very strange problem, it only happen to one SQL Server, other
SQL Server seems to be fine

I got the following error when trying to run a sp against one of the
SQL Server:

SELECT failed because the following SET options have incorrect
settings: 'QUOTED_IDENTIFIER'. Verify that SET options are correct for
use with indexed views and/or indexes on computed columns and/or query
notifications and/or xml data type methods.

If I put the SET QUOTED_IDENTIFIER OFF In the beginning of the sp,
everything works fine, but the questions is why should I do that? and
why it only happen to only one SQLServer ? The database option on
QUOTED_IDENTIFIER are off on all SQLServer. (I am using SQL2005)

Thanks in advance.

if db_id('testdb') is not null
drop database [testdb]
go
begin
