I guess I'd have to ask why you think that's important? If the server's name isn't resolvable in your External DNS, and your internal network is protected by adequate security, there's no danger of the machine being abused. If your preimeter security is breached it won't take much longer than 30 seconds to find the server -- but at that point you'll have much bigger problems to deal with. --- Rich Matheisen MCSE+I, Exchange MVP
