Well, that and ... even with a randomized machine name, it'll either be 
advertised via Samba services and/or still accessible by its IP address.

If someone wanted to find the machine on the network, they'd run a tool 
similar to nmap or nessus to scan a block of IPs for open services.  I bet 
that as I mention this someone's going to go and have fun with these toys 
... be safe and respectful. ;)  Assuming the system communicates via IP, 
obscuring the machine name has no real bearing; it still has an IP addie.

I'd recommend IPTABLES to firewall off a box.  Google for more nfo.
