A Group Policy setting found at User ConfigurationAdministrative TemplatesSystemUser ProfilesLimit Profile Size can be used to limit the size of roaming user profiles, but this setting has a hard-coded maximum of 30MB. What if you need to allow roaming profiles to exceed this limit? If your client computers are running Windows Vista then you’re in luck as you can use Folder Redirection to reduce your profile size by redirecting hefty folders such as Documents, Music, Pictures etc. Folder Redirection and Roaming User Profiles can work well together, see Chapter 14 Managing Users and User Data in the Windows Vista Resource Kit for more info.
