Thank you for the response. I know there is an IP mismatch. That, I get. What I
need your help on is how I tell samba to forget about the old IP address of
192.168.7.127 and learn the correct address for Adrienne-PC? Where is this
cached and how do I get rid of it?

Samba isn't seeing something correctly. For example, here is the same problem
with a machine named reception (in the reception area):

Jan 13 12:43:19 nemesis smbd[7449]: Matchname failed on RECEPTION.rbpllc.com
::ffff:192.168.7.150
Jan 13 12:50:46 nemesis smbd[7474]: [2010/01/13 12:50:46, 0]
lib/util_sock.c:1564(matchname)
Jan 13 12:50:46 nemesis smbd[7474]: matchname: host name/address mismatch:
::ffff:192.168.7.150 != RECEPTION.rbpllc.com
Jan 13 12:50:46 nemesis smbd[7474]: [2010/01/13 12:50:46, 0]
lib/util_sock.c:1685(get_peer_name)
Jan 13 12:50:46 nemesis smbd[7474]: Matchname failed on RECEPTION.rbpllc.com
::ffff:192.168.7.150

Samba is saying there is a mismatch between reception and the IP of
192.168.7.150 -- but that is WRONG!

13:19 nemesis:~> ping reception

Here is the dns entry:

and the reverse:

[13:23 nemesis:/home/david] # cat /var/lib/named/dyn/192.168.7.zone
$ORIGIN .
$TTL 172800 ; 2 days
7.168.192.in-addr.arpa IN SOA bonza.rbpllc.com. root.bonza.rbpllc.com. (

101 PTR rankin-p35a.rbpllc.com.
<snip>
$TTL 14400 ; 4 hours

So why is there a mismatch error filling my logs?
