Win XP Pro - IP Address won't auto renew when changing sites

[tmmiller]

I have an end user who uses wireless at her office. When she shuts
down and goes home, she will connect up to her home wireless however
she will still have her office IP address. (It's not static). She can
do an ipconfig /release /renew just fine and it works, but she would
like it to auto renew/change when starting the PC.

I have removed and re-added TCP/IP and removed/ re-added wireless
drivers. I am at a loss as i've never seen it not refresh the IP
address when powering up the PC.

Any help is very much appreciated.

The two wireless networks must have a different SSID ( name ), so I
don't see how an IP Address from one network would be retained as
the machine detects and joins a different wireless network.
If you check the available Wireless networks ( assume the PC uses
XP's Zero Wireless Configuration ) what networks are shown. Also
which is the preferred network. Also does she power off the computer
or simply put it into a Sleep state ?
