Your DHCP server should supply the IP address (not a domain name) for the 
name server you are supposed to use.  You shouldn't have to create 
/etc/resolv.conf manually.

If the name server that you are supposed to use is 1.2.3.4, then your 
resolv.conf should have a line that looks like:

nameserver 1.2.3.4

Typically, you will also have a line that lists domains to search in order 
to resolve host names that aren't fully qualified.  It would look similar to:

search firstdomain.com seconddomain.com

But again, that line isn't required.

To run the client, all you need is a line in your rc.conf that would look 
similar to:

ifconfig_fxp0="DHCP"

where fxp0 would be replaced with whatever the device name is for your 
ethernet interface.
