bwhitehd is correct. With samba you can set up "roaming profiles" for your domain clients. The samba documentation bwhitehd and bforest posted a links to will tell you how to do this. My documents wont be the only thing on the server though. There entire directory under Documents and Settings on XP and Users on Vista will be on the server. Users tend to enjoy this because their desktop and application settings follow them to different machines as well. Your client support personnel will love this because it is less time spent helping users set up email, office, etc.
