This is the script you can force over Host / SQL .  Copy it in the sql check the checkbox run as script.

*** Start Script ***

UPDATE {databaseOwner}[{objectQualifier}Forum_Users]
SET IsTrusted = 0 WHERE IsTrusted = 1

Go

*** End Script ***

After this you must known all users are now not trusted users.  You can manual setting some users as trusted over the Forum Manager.

Thank you for the script as the response.

It seems that the checkbox of 'trusted' or 'not trusted' for a new User indicates that the User is 'trusted' from the beginning, but this is not what shows in the database. Then the first time I hit 'update' for ANY field in the Forum User Settings for any User, there is an ugly side effect that that particular User is changed from 'not trusted' to 'trusted'. As far as the Administrator can see, the User is trusted from Day #1 because the box is checked. As far as the database administrator can see, this is not true, and the User only gains trust when the Administrator makes ANY change to their Forum User Settings. Administrator is not able to edit the check box. Ideal situation would be that it should check the status in the database. The determination is forced by the code in the application to be checked regardless of the status inside of the Forum User Table for that specific User.

Thanks
