Vista reports 00-00-00-00 as MAC address in ipconfig

Nizaris asked on
When i do ipconfig /all i get tons of network adapters. The one that is active and that i use as my internet connection under MAC address it lists 00-00-00-00-00-00. Yes my network card works fine in device manager, as does my internet.

This software i'm trying to connect to however uses some kind of software MAC filtering (i can only assume), it has the client software send my MAC address to the server and unfortunately Vista x64 reports mine as 00-00 which prevents me from accessing it, it does NOT look at the packets itself afaik.

Why is vista incorrectly reporting my MAC address while my network card works fine ? How could i find out what is causing this issue if it's not a vista bug? This is apparently a widely known issue as many users with Vista can't access this software. Is this issue fixed in Win7 ? I hear XP doesn't have this bug but i don't want to downgrade !

Thank you for your time.

Hi Nizaris,


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!
