OT, but Consumer Reports has long advised that oil changes more often than the mfrs recommendation are a waste of money. And if you use synthetic oil, you can go a very long time between oil changes.
If we had a dedicated BES server I'd follow your advice about always rebooting after install. Since we don't, I guess I can schedule an automatic reboot the night after the install. But it's nice to know up front if it actually REQUIRES a reboot, because then I'd know I need to do the update after hours.
Wonder why they can't stamp the new BES version on the database during setup? That seems odd. And if they can't, and BES services startup doesn't do it either...what in the world does? MSDE startup? Very odd.
