Vista reports 00-00-00-00 as MAC address in ipconfig
I would suggest you to check it again because, we do have “Tunnel adapter Local Area Connection” listed but with Physical Address: 00-00-00-00-00-00-00-E0.
I have checked several computers with it.
Tunnel adapter Local Area Connection is meant for IPv6 configuration.
Anyhow, to remove “Tunnel adapter Local Area Connection” and consequently the Physical Address: 00-00-00-00-00-00-00-E0 from ipconfig /all
1. Click Start, type cmd in the “Start Search” box, right click the cmd.exe, and then click Run as Administrator.
2. In the Command Prompt, type netsh int isa set state disabled, and press Enter.
Hope it helps!
