while doing other things, ie, adding a hosts file to block certain IPs, I found a MS sample hosts file in my w2k ..\etc dir which included the entry 22.214.171.124 which has some relation to DCS but I was not sure which DCS app. I removed the "sample" hosts file and inserted the custom blocking hosts file, and all runs ok, but then I used Firefox to open some URL (not particularly related to anything) and Zone Alarm popped up asking if I wanted to let Port Explorer accept connection from interent, my local broadband provider DNS. I said ok, and then I checked ZA and it was already configured with Port Explorer having permission to connect to the internet, so trying to figure out the relationships: 126.96.36.199 (Liquid Web) to DCS and Port Explorer, and why ZA seemed somehow confused about all this. I guess that Port Explorer needs a DNS to resolve info and it was using DCS DNS but now it is using my local DNS. assuming that is essentially correct, is that a problem? if I'm incorrect, please explain. thanks!
