I have two routers and a cable modem with several computers. However, the
machine colocated with the cable modem can't "see" the ones downstream,
though they can "see" (at least PING) it. I thought I set up the network
identically on each machine but don't even have a network access icon in the
taskbar on that one machine.

None of the machines "see" each other in Network Neighborhood, nor do they
"see" what's in their workgroup. They have, of course, been assigned to the
same workgroup.

What's going on here?

Why do you have two routers? If you have two routers, I would expect the
results to be exactly as they are - two separate networks.

If what you really want the second router for is more wireless coverage, you
need to turn off DHCP on one of the routers and turn it into a wireless
access point instead or if wireless isn't desired disable that capability in
the router as well as DHCP and just use it as a switch.

Then all machines will be on the same network and can share files/printers.

Well this isn't entirely clear. There's a 50-foot cable between the two
routers, and, initially, I wanted a wireless link, but, having now routed a
cable between office and lab, I merely want to use the added ports on the
second router. If that's using it as a switch, that's now now it's
configured. However, the problem persists. I have disabled the downstream
router's DHCP, so, presumably, the first router will distribute NAT
addresses.

Is that what I should have done?

Yes, with the caveat that the cable from router 1 to router 2 must
connect to one of router 2's LAN ports. Leave the WAN/Internet port on
router 2 open. You might also want to configure router 2's LAN-facing
IP to be in the same subnet used by router 1's DHCP server but outside
the range of addresses allocated by that DHCP server.
 
I've done that ... BUT ... the resources on the remote computer are still
not accessible, though they themselves believe they are shared.

What am I doing wrong?
 
Hi
Check the IPs of the computers, and make sure that they are all on the same
subnet.
I.e. the first three groups of each computer's IP number must be the same.
If they are all on the same subnet undo and redo the shares of the
downstream computers.
If they are Not on the same subnet read these two pages.
Using a Wireless Router as a switch with an Access Point -

Network Segregation - http://www.ezlan.net/shield.html
The pages where written for Wireless, but the same logic applies to Wire
too.
