Vista - Automatically setup outlook 2003 with exchange settings

I want the best way to accomplish this. I want the exchange settings
to be automatically be set once you login to the username on the
domain. So no matter what computer the user logs in, Outlook will be
ready to go without
inputting settings manually.

I have created a prf file and tested it with a virtual machine on the
domain and that worked.

Now what i want to do is be able to use the prf file on one 2003
server and use this on other sites where they have their own exchange
server on the same domain.
