I've been using pdnsd on my ubuntu system for about six months. It has definitely improved the time needed to resolve web addresses. I am having a unique problem though. For some reason, when pdnsd is running I cannot resolve the address for www.tigerdirect.com. I get "server can't find www.tigerdirect.com: NXDOMAIN". When I stop pdnsd, the address resolves. I assume that I have a configuration problem. Can anyone suggest what I need to change? So far this is the only address that I've had a problem with.
