If you want to use an existing external NIS service you must change the domainname and the file /etc/yp.conf on each compute host to give the correct domainname for your external NIS service and ypserver. See the section on firewalls. The domainname is typically read from the variable NISDOMAIN in the file /etc/sysconfig/network on each compute node when it boots.
