You can set the name of your computer in /etc/sysconfig/network ; mine reads

NETWORKING=yes
HOSTNAME=mary.gayleard.com

Also check /etc/hosts on all the computers in your network.

ifconfig will tell you what IP address has been assigned to your machine
by dhcpd;
you can probably change this by editing /etc/dhcpd.conf on the machine
acting as dhcpd server, eg I have

        host elizabeth {
                hardware ethernet 00:02:2D:21:03:E7;
                fixed-address 192.168.2.11;
        }
