Bad netizen! Not you though... :) It will work, but will put additional/unnecessary workload on the Internet root servers. > we can't resolve/get A > record of our website that is hosted in our ISP. other parts of the world > can see our website, but we from the inside can't get the A record, thus, we > can't view the website. Your root hint file is outdated. In Linux: # dig > root.hints Should fix it. I don't know the comparable commands in windows. When I was working in the ISP "Golden Era" business in the Phil. few years ago, we get roughly the same problem as you have now. What happened was some of the IP Address of the root hint servers have changed. Everybody can resolve one site, but we can't. Running the command above and cronned it every two weeks solve our problem. > is it OK to use root hint servers? what is the catch? See above. > or should i use our ISP's nameservers? Definitely.

You're on the right track, that's exactly what you need to do. You can have multiple forwarders like your ISP DNS server and OpenDNS as what others have mentioned. But: * If you have MS AD, then you might have to coordinate with windows guys to implement this. * Administrative roles. Putting Linux in is easy, but in the long term goal, you should have someone or you do the Linux System Administration tasks. If you are busy, this might not want you want. The easiest then for a short term goal is to instruct your ISA proxy to use your ISP DNS server or Opendns in the first place. -- regards, Andre | http://www.varon.ca _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
