[Blind-sysadmins] Win 2k3 64 and screen readers

Hi all, I have inherited the responsibility of managing a Dell PE 2900 with Win 2k3. Since it has 8 gigs of memory I assume it is the 64 bit version of Win 2k3. Does anyone know what screen reader(s) I can get to work on it. Can the 64 bit version of JFW work in this scenario? Also on a related note if I have the service tag from the server is there anywhere on the Dell site where I can punch it in and find out just what equipment it was built with? Thanks Frank
