Windows 2000 introduced a per-user local settings folder into the user profile that is not copied during log on or logoff. This folder is intended for the storage of operating system components and other applications can store non-roaming per-user data. A typical example of the usage of this folder is for Microsoft Internet Explorer to store a users Favorites in the roaming portion of the user profile but store the Temporary Internet Files in the local (non-roaming) portion of the user profile. This will allow a user to retain access to their favorite URLs, but will save copying of temporary cache files at logon and logoff.

On computers running Windows Server 2003, Windows XP or Windows 2000, the History, Local Settings, Temp and Temporary Internet Files folders do not roam by default. Other Non-Roaming Folders are configured using the Group Policy Object Editor. The path for this setting in the Group Policy name space is:

User ConfigurationAdministrative TemplatesSystemUser ProfilesExclude directories in roaming profile

Once enabled this allows multiple folder names to be defined, all relative to the root of the users profile. Once included in the policy these folders will not be copied to the local machine at logon, nor copied back to the server at logoff. This setting is likely to result in decreased time taken for a user to logon, by restricting the amount of data within a user profile that really does roam with the user.
