I remember this from a while back - it's a default permissions issue. You have to enable remote anonymous login, or something - I can't recall exactly. The tab shows fine when you log in locally, right?
i have found the mistake. When you connect via RDP you have to set the switch /console in the RDP Session when you come from a 2k3 Server. If you come from a 2k8 Machine the switch has the name /admin. Then you have Console Permissions and see all the tabs you want.
Wish you all nice christmas !
