I have a small (6-10 machines) network behind a Linksys router,
connected to a cable modem. As is common, the router gets the DNS IPs
from the ISP, and my local boxes get the DNS from the router, which
also assigns IPs in th 192.168.0.xxx range.

I need to assign fixed IPs to some of the machines, but when I do, the
option to obtain a DNS address automatically is disabled. This seems
to be what many networks would need, but I don't see how to do this.

Generally the DNS would be the IP# of the Linksys box (192.168.0.1).
Yes, you have to statically put it in there.
 
Thanks, that seems to work, at least on a couple of machines so far.
I didn't realize I could point to the Linksys as the name server,
instead of just the place to get the DNS server address from.

I don't see any DNS config options in the Linksys; is that implied as
part of bring a router?

No.
The Linksys Box acts as a DHCP Client to the IPS and receives all its
Extenal TCP/IP Config from the ISP, which includes the DNS IP# for the ISP's
DNS. The Linksys box simply takes DNS queries from your computers that it
receives and passes them on to the ISP's DNS and then returns the results
back to your computer. So as far as your computers are concerned the
Linksys Box is the DNS server even though it really isn't.
