Hi Francesco,

Firstly I would get the server off the network, litterally pull the plug
on the network cable. Then dig through logs, etc, and try and find out
how they got in, hopefully you had really good logging set up on this
machine, so you should be able to get a fair idea of how they got in.
I would personally say that I re-install is your best way around this,
as you have no idea how many backdoors have been installed on your
server, or what else for that matter.
I hope that the DVD's were at least one's that you hadn't seen?
