Hi,

NIS administers the IPaddress-to-name tables only.
If your client needs a new IP-address, it has to be changed locally: Most server don't use DHCP.

The change of data for NIS-tables is performed only on the NIS-master itself. After the 'yppush' (e.g.) als NIS-servers share the same updated information.

Next: your output shows no usage of NIS.
- maybe your system seems to use just the plain /etc/hosts file. Look/change the line starting with 'hosts:' in the file /etc/nswitch.conf
- perhaps 'files' is found before 'nis' and you did include this host into the local /etc/hosts file? So the old data is found first.

You need to do two things
1. Change the IP address in the host itself. You need to use the "/sbin/set_parms ip_address" command (requires reboot). Before rebooting check the /etc/hosts and /etc/rc.config.d/netconf file to ensure that IP got changed.
2. Change the NIS map for this hostname. You need to go on the uk204 server and modify its /etc/hosts file and change the IP address of your NIS client and then push the change by running "ypmake hosts"

Ensure that step 2 above is done on the NIS master. It is not clear if u204 is the NIS master or the server that you ran the nslookup command from.

Finally one last thing. Check http://forums11.itrc.hp.com/service/forums/helptips.do?#28
