In the DNS-HOWTO I was told I should have "search turnbui.com" in my resolv.conf. Is this true?

Last night at 11:56pm I started getting server failures on DNS queries. I noticed that the Win-XP box was approx 4 miutes faster so I reset it, rebooted and all seemed OK.
I also noticed on checking output from a DNS-HOWTO that I had an extra line in the output from my
dig turnbui.com axfr
command namely "turnbui.com. 86400 IN A 192.168.1.7"
and thinking I had an error used nsupdate to delete it?
I then went to bed and now when I try to use nsupdate to update delete/add it complains that it can't find Server turnbui.com!!?

couldn't find server 'turnbui.com': Name or service not known

Since I never had a line like this in my /named/zone/ files and I can't use nsupdate to add it back I'm lost.

Can someone help with this and the resolv.conf question please?

Thanks
