I'm not surprised, as it's quite a specific issue, and doesn't really illustrate any one possible point of failure. > I have two computers, desktop and laptop, and a wireless router and > ADSL > modem.

Furthermore, when asking questions like this, it is often handy to include the output (or at least a link to it) of the: route -n command, from BOTH machines, as well as: ifconfig -a from BOTH machines. > I've tried adding the appropriate IP values (192.168.0.20 and > 192.168.0.22) to the respective /etc/hosts and /etc/hosts.allow, but > it > makes no difference.

I suppose at an outside edge, you could check your /etc/nsswitch.conf to make sure that the values listed there are sane, however, I suspect that it's more a routing issue on your part.
