[KLUG Members] WINS using old IP address question

[bill]

Sometimes when I log in to a network with a computer I get a different
IP address than I did logging in last time with the same computer.  This
might happen by logging in wirelessly or logging in remotely with
OpenVPN.

For example: 

First time:  192.168.0.100
Second time: 192.168.0.200

The network has a SMB server and a WINS server.

When I do 

smbclient -L mycomputer

it tries to connect to the old IP address, even when the box is on the
network with a new IP address.

Where do I look to find where it is storing this old IP information?

How do I get it to -check first- before it tries to connect to the old
address?

Is there a way to announce when logging in, "Hey, I'm over here now!"  ?

kind regards,

bill
