This is a bonus tip based on the recently posted Mount server volumes using location files, but it is so useful I thought it deserved its own tip.
Once you have created a Location File using the method explained in said tip, add that file to your Login Items on the Login system preference pane. Next time you boot or login, the referenced network drive will be automaticly mounted.
Best of all, this method works with servers that don't allow passwords to be saved to the keychain.
