Thanks to everyone who has responded.
Tried disabling IPV6, the problem remains. I've done checks for viruses
and malware, everything comes up clean. The machine is using local DNS
servers, and the default hosts file.
At this point, I feel like the most satisfying solution would be a big
hammer but alas, I'm guessing that wouldn't go over very well. I'm
tempted to just do a clean reinstall of the OS, I'm betting there's a
good chance I wouldn't see this problem again, but I hesitate to do that
without understanding what's going on in the first place.

You can try the suggestion in the last post in this thread:
if that works I'll let you pass it along to NAG, but I didn't want to
spam them a solution I hadn't tested.

Subject: [MSUNAG] Dnscache in Svchost using over 60% of CPU?
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
