Need alert that underlying IP address no longer matches node name

I've run into this a number of times:
-User installs Membase on his laptop or development system
-Everything is running fine until some time later when it stops working
-User calls support
-Perry spends days back and forth trying to figure out what's going on
-Perry finally remembers that some systems have DHCP and their IP address will change without Membase realizing it
-Perry tells user, problem resolved.

Can we please add an alert in the UI that tells the user that their system is likely nonfunctional because the node name is no longer reachable?
