remove Microsoft AU Helper, Microsoft Database, and Microsoft Entourage from Login Items under your account for starters. I don't know why you have all those in login items; I only have 2 things starting up in my login items.
better yet, maybe you should remove everything from login items.
From <http://www.entourage.mvps.org/glossary/index.html#au_daemon>:
Daemons. ... Microsoft Entourage uses the Microsoft Database daemon and the Microsoft AU daemon.
Microsoft AU daemon. The AU daemon is associated with the Microsoft AutoUpdate application. That application can be set to check for updates to MS Office at particular intervals. It does so by way of that daemon.
AutoUpdate (MAU). Microsoft AutoUpdate (MAU) application will automatically check for updates. .... When you select to
automatically check, MAU will install the Microsoft AU daemon in Startup Items.
From <http://www.entourage.mvps.org/glossary/daemon.html>: ... If you have Office Notifications/Reminders enabled you will see the database daemon in your startup items.
The conclusion seems to be that if I want to eliminate these from the startup login items, I should simply trash MS Office, which seems like a rather extreme attempt at a "solution" (notwithstanding my lack of love for MS as well as the fact that Office 2004 is a Carbonized set of apps).
