My DHCP server is only giving out an IP and reservation to one server for
pxe boot purposes and nothing else.

This is the DHCPD.conf file

ddns-update-style interim;
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.0.0;
option broadcast-address 10.60.255.255;
option routers 10.60.0.5;
option domain-name-servers 10.50.1.56;
option domain-name "domain.com";
option ip-forwarding off;
allow bootp;
allow booting;

subnet 10.60.0.0 netmask 255.255.0.0 {
}

host host.domain.com {
hardware ethernet 00:24:E8:5C:12:93;
filename "pxelinux.0";
fixed-address 10.60.1.60;
next-server 10.60.1.49;
}


any ideas?

If the server is going to assign IP addresses, you need to tell it what
range of IP addresses it can give out, for example:

subnet 10.60.0.0 netmask 255.255.0.0 {
range 10.60.0.2 10.60.255.254;
}
If the LAN contains some hosts with fixed addresses, they should be
declared.
