Many users need access to their e-mail from different Microsoft Exchange Client computers. For example, a roving user can have offices in two different locations. You can make it easier for a roving user to log on to a new Microsoft Exchange Client computer by using the automatic profile generator to create a default profile. If you preconfigure a default profile, roving users do not need to create a profile using the Profile Wizard every time they log on to a new client computer because the automatic profile generator creates one if needed.
To create profiles for roving users automatically, you can create a .prf file with the user's logon name and home server defined. You can also configure the logon script to verify that a profile does not exist for that user on the computer. If the computer doesn't already have a profile defined for the user, the logon script calls Newprof.exe. Newprof.exe uses the .prf file in the user's home directory to create a new profile.
