At what point in the scan did you get blocked? It looks like the portscan worked, except that there are a whole lot of ports I'd not expect to see on a server like that. Things that stand out are the presence of VNC with Terminal Server AND Metaframe, for example. And Metaframe on 2000 Advanced Server seems like a terrible idea as well, from what I know of the way it handles foreground/background priority, and how it's optimized for specific types of server apps. Are you sure that there isn't some kind of reactive (firewall or IDS) configuration that's meant to throw you some red herrings that automatically block you when you connect to them?
