Profiles

I posted this in the discussions area and got no answer, I have a laptop that I plug into a port replicater which connects me to my network. I use outlook for e-mail. I set up my profile on outlook and everything works fine. If i reboot my laptop i lose all of my profiles I may have set and have to start all over again. Where are how do I set up the profiles so that when I plug back up to the port replicator or reboot my laptop, I retain any profile setting I have set up?
