It's a server in my home network and already behind a Linux gateway. It's never been compromised and has been running fine needing no attention. I know W2k is old, but this one just works and I don't intend to replace it just because of this update while the old client still works. Especially since the fix should be pretty simple (I already provided details in another thread).

And don't get me started by implying "Linux is safe by default"; for the sake of a civilized discussion, I'll assume you were trolling.
