Roaming profiles As a network administrator, you'll find the roaming profile much more useful. As the name suggests, a roaming profile follows the user around the network from workstation to workstation. Unlike local profiles, your workstation obtains roaming profiles from the server. It then copies the profile to the workstation and loads it, displaying the user's preferences. Don't use network profiles on workstations that are going to pull profiles across slow WAN links.
User profiles can range from several hundred kilobytes to several megabytes in size.
If users try to load their profiles across slow WAN links, they'll be frustrated by long startup times. To solve this problem, either store your users' local profiles on a remote workstation or place a server at the workstation's remote location to store roaming profiles closer to it. Mandatory profiles You can control some of the anarchy that user profiles create by using mandatory profiles on your workstations. Mandatory profiles replace the changes that users make to their user profiles with settings that you want every workstation to have. If a user's setting conflicts with a setting in the mandatory profile, the mandatory profile takes precedence.
