Who is their ISP? Is your client using their DNS servers? I was having a
similar problem where intermittenly we would lose the ability to resolve
DNS. If I put in the website's IP I could get to it. This happened
sporadically at best and often resolved itself within an hour (talk about
frustrating). Last time it happened I changed the priority of the DNS
servers (made my ISP's "primary" my secondary and made their "secondary" my
primary) and so far everything has been working pretty well (for about a
week). Let me know if this works for you.

Thanks,
Phil
