Having an issue on a Vista Business box. Long story short, a case of very high CPU utilization. I tracked the culprit down to the DNS client service (Dnscache), but that's only half the battle. Now that I know Dnscache is the offending service, what to do about it? This machine is part of my domain. As far as I know, no other machines on the domain are exhibiting the same issue. I tried doing an ipconfig /flushdns, but that didn't matter. Anyone have ideas as to what might cause this and what I could do to fix it?
