Dynamic DNS
1. WinXP laptop connects via ethernet and is assigned ip address = 192.168.80.20.
2. Laptop connects via wireless and is assigned ip address = 192.168.80.13
3. nslookup shows laptops addresss = 192.168.80.13. CORRECT.
4. Laptop disables wireless connection.
5. nslookup shows laptops address = 192.168.80.13. INCORRECT.
How do I configure the laptop to perform ipconfig /registerdns when the state of the network adapter has changed?
When the wireless network adapter was disconnected, the laptop should have performed a registerdns, but didn't. Therefore, the dns entry was still showing the old ip address for the wireless connection which had been disabled.
