Okay, so what exactly do you need to do?

If the HP system is only a client, then you don't change any DNS entries on it. The only thing you can change is the nameservers that you point to or the default domain or search list.

Example of /etc/resolv.conf from man page on HP (man resolv.conf OR man resolver):

A typical resolv.conf file resembles the following:

domain div.inc.com
nameserver 15.19.8.119
nameserver 15.19.8.197
