csrss is the Win32 subsystem executable.  It has to be running if you're to
run any Win32 programs.

If the message box is visible then the process will still be running.

VNC Server doesn't do anything when your IP address changes.  It doesn't
have to - it's listening for connections from any IP, so it just continues
doing that.
