I work in an office environment with 2 DNS servers, both virtualized. We’re having some problems right now with the occasional but still very annoying dropped, lost, or otherwise failed DNS queries. This problem started shortly after we switched ISPs. We’re not sure if the problem is entirely on their end, entirely on our end, or somewhere in a clash between their configurations and ours. What we’re considering doing is no longer forwarding DNS queries to our ISP, but instead looking to use the Root Hints instead. I just want to be sure as I can be that this will not have any severe or unforeseen impact on our environment. Has anyone else made this switch and had any issues as a result of it?
