I ran a set of 4 Win 2k servers with CF 5 and Windows NLB. It's fine except for one thing....
If one CF instance crashes, port 80 on that server goes idle... The NLB load balancing is not application aware and therefore thinks that the idle server can stand some more load and so redirects all the incoming requests to that dead server... Port 80 is alive but CF has crashed and therefore doesn't respond. At this point, your entire site appears down because one server in your farm has gone down... :( I've seen this happen many times with CF5 and below. With CFMX 6 and above I have much more confidence that this is less likely to happen as CFMX is so much more stable than CF 5 ever was. That said, if you are looking to restart a CF server, its best to take it out of the load balancing group, restart it and then add it back in to the load balancer to make sure your site stays up for the duration...
