This is a change introduced in Windows Server 2008. Users can't change their font sizes using the standard Windows option - it's locked down to admins, on the basis that it's a server wide setting. We Citrix \ terminal server people know of course that per user settings are needed (as it was in 2003!). This is the same in R2. We engaged Microsoft and developed a utility that allows users to change their font sizes. It basically imports in registry keys that set the font sizes, depending on what option they choose in the utility.
