If I'm correct in order for this to work you need to be physically at the
server. If you need to do a remote attack then this isn't going to work. I
know I found an accout on the client machine that provided admin access and
used that account to dump the registry into L0phtcrack and I also managed to
place VNC on the system so I could run local commands on the server.

Subject: [PEN-TEST] Dumping NT password hashes from memory

i remember seeing a demo at blackhat where some guys were able to dump an nt
password hash from memory and then reloading it with a different one loaded
from pwdump and using it to log in remotely into another server. here's how
it works;

1) run pwdump on victim machine to retrieve password hashes for say User1
2) create an account on your local machine called User1 and log into it
3) run this tool on your local machine to unload the password hash for User1
and replacing it with the password hash from pwdump.
4) net use to the remote victim machine as User1 with the victim password

does anyone have more information on this?
