Terminal Server and Roaming Profiles

I am setting up a Windows 2k server with Terminal Server. I would like to find out everything I can possible find out about setting up Roaming profiles. I have read some about it and know its possible but would like to get advice from anyone who knows more about it, or if someone can point me to some good research on it I would appreciate it. The set up I will have will be a file/exchange server, a terminal server, and a proxy server.

Thanks,
Shane Kenny
