R2 beinhaltet eine Reihe an Verbesserungen und neuen Features (s.u.). Derzeit sieht es so aus, als ob Windows Server 2003 R2, im Sommer bzw. im Herbst des nächsten Jahres erscheinen wird.
- Active Directory Application Mode (ADAM). A light run-time mode for Active Directory designed specifically for deploying secure, directory-based applications.
