Change transaction safety mode

    I am using SQL 2K5 standard with sp2 and am testing db mirroring (no withness). Because our two servers are in a workgrouop, I set up the database mirroring using TRANSACT SQL statements not the management studio tool. It is working fine that way.

    By default, transaction safety is set to FULL which is sychnronous. The options are grayed out in the db's mirroring properties window. How do I change it to OFF which is asynchronous. The BOL shows me that I can issue "ALTER DATABASE <database> SET PARTNER SAFETY OFF" on the principal server but when I issue the statement, I got an error "This SQL Server edition does not allow changing the safety level. ALTER DATABASE command failed.".

    Please advice.
