Can NOT resolve DomainName

[Jeremy Fowler]

Your /etc/resolve file is probably your problem. However, Redhat should get that
information from DHCP and fill in that file for you. I would make sure your
setting up your NICs using the recommended Redhat init scripts. Look at
/etc/sysconf/network and /etc/sysconf/network-scripts/ifcfg-eth0 and make sure
everything in there is correct. Don't know what to look for? RTFM! Then make
sure the network init script is in your current run level. Use tksysv, ntsysv,
or chkconfig to see what is enabled.

Also, If your SMC router is your DHCP server, how does it get it's IP address
from roadrunner? Is it manually input or does it use DHCP itself? Open up your
router's configuration and check to see if it is configured with DNS information
and make sure that information is being pushed forward to you.

As a last resort, you will have to edit /etc/resolve on your own and enter that
information. You can use any editor you want. Some common ones are emacs, pico,
nano, vim (vi), and joe. Vim is not very intuitive for a Windows user, so I
would stay away from that one.
