[framework] can there be a succeeded exploit?

[Prince Brave]

Hello,everyone!
I am a new member.I am running
Microsoft windows 2000 5.00.2195(advance server 2000)
on vmware .I never patched the system ,I began my learning from using 
the lsass MS04-011 exploit, and use the add user payload,but my server 
just prompt and reboot then,I feel upset,because it seems that I didn't 
make a succeed exploit.So can anyone offer me a usable exploit and let 
me join the exploit world happy?
Many thanks,
Prinbra
