Windows XP: Missing Authentication tab
If you’re setting up 802.1x on your Network connection but can’t see the Authentication tab, make sure the “Wireless Zero Configuration” service is running.
- Start > Run… > services.msc
- Find the Wireless Zero Configuration service.
- Right click on it, and choose “Start”.
The Authentication tab will then appear on your Network connection properties.
Yes, I know. But apparently, to get 802.1x support, you need to enable a Wireless service, even though you may well be using it on a wired connection. Intuitive, eh?

Actually, it’s the Wired AutoConfig Service that shows (enables/disables) the Authentication tab under Network Connection properties.
