(Actually, this particular interfaces file is from a totally different
machine, but it also has the same symptoms. Also, when I booted this
machine up with a Knoppix LiveCD, it too go the bogus Belkin DNS entry
in resolv.conf. So I now know it's not machine- or Debian-specific,
although it might be Debian-derived-specific.)

That's the way it seems to me also, but when Belkin support told me that
their router does NOT offer its own address as a DNS server, I figured I
better double-check with other Debianistas before concluding that Belkin
support doesn't know what they're talking about.

I don't find any such settings; here's a snapshot of the only relevant
page on the Belkin setup that I can find:

Ag! I'm so dense. I'm so accustomed to being a Debian-only house that I
forgot my work laptop is dual-boot with Vista. I'll give that a shot.

Thanks for the response! I appreciate it!
