When making changes to the User account, security property page, on a Microsoft Small Business Server 2003, the changes that are made are gone the next day. If I add a user account and assign "send as", or even if I change an existing account or group object, the changes are saved for a while, i.e. I can close it, open it immediately, and the changes are still there. But if I open it the next day all changes are gone. The user accounts are in the default OU.
