I'm now thoroughly confused. :( I thought disabling DNS Caching or disabling the DNS Client service are, essentially, the same thing. These articles "seemed" to recommend disabling one or the other (which, I thought, was the same thing). I do understand your comments (and I don't disagree as I don't have enough information, e.g., who is John Navas, etc.); yet, I do make daily use of a very large hosts file (and for good reason). So, I enabled the DNS Client service (as per recommendations here). However, I just realized I also use Comodo which has an option to use THEIR DNS servers. Do you think this "feature" is partially the cause of what we're seeing?

This is Comodo's description of the "Comodo Secure DNS Configuration" feature! Comodo Secure DNS - Another free service intended to provide you with a safer, smarter, and faster Internet: - Websites load faster because your domain name requests are resolved by our worldwide network of fully redundant DNS servers - Highly secure infrastructure reduces your exposure to DNS Cache Poisoning attacks - Parked, not in use, or commonly misspelled domains are automatically detected and forwarded If you use Comodo Secure DNS Servers: - Your computer's primary/secondary DNS settings will be changed to 156.154.70.22, 156.154.71.22 If you are in a corporate network or using VPN connections, then contact your administrator before enabling this option to avoid potential connectivity issues.

Kat, read my responses to those links. In addition to Char's responses, which I agree with, you should really leave the service alone. I made some other recommendations. And good question about your scenario. Is this a home machine, or a machine on a corp network? Ace

I hope someone will correct me if I'm wrong, but I assumed the DNS Client service performed local DNS caching as one of its duties, so in that respect they are related. >I do understand your comments (and I don't disagree as I don't have enough >information, e.g., who is John Navas, etc.); yet, I do make daily use of a >very large hosts file (and for good reason). > >So, I enabled the DNS Client service (as per recommendations here). > >However, I just realized I also use Comodo which has an option to use THEIR >DNS servers. > >Do you think this "feature" is partially the cause of what we're seeing? No, I don't think it's related. You can use an application called Namebench to test multiple DNS servers to see which are fastest for you. http://code.google.com/p/namebench/
