Nameserver and Rosalba
I tried modifying the nsswitch.conf file to include going to dns in addition to local files for everything (services, network, etc) and then moving the /etc/hosts file to /etc/hosts.bak. Unfortunately, this still didn't allow front-ends to reboot properly. So I'm not sure what is using the hosts file, but whatever it is, is apparently important. After the test I placed the hosts file back and reverted the nsswitch.conf file.
I also noticed that Rosalba was having problems connecting to the network. This apparently was because I had shut down the dhcp server on the NAT router, as had been discussed at the meeting on Wednesday.
To fix this, I modified the /etc/sysconfig/network-scripts/ifcfg-eth1 file to fix rosalba's ip as 188.8.131.52 (which doesn't seem to be in use). I also updated rosalba's /etc/resolv.conf file to point at linux1's name server, and two additional name servers as well, and added the "search martian" line. I modified the /etc/sysconfig/network-scripts/ifcfg-eth0 file so the built in network card doesn't come up automatically, since its currently not plugged into anything. Lastly, I added rosalba and its IP to linux1's name server files.
