"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You could download a well know free little utility from Sysinternals called RegMon. Install and run it, and then make the change. It will show you which key was accessed.

RegMon will display a lot of activity, you can right click on unnecessary activities and filter them out to simplify the display.

You can also use regshot, makes a snapshot before an action and compare afterwards. Doing this for your option gives the following result:

Julie, were you able to disable the IEEE 802.1x authentication ?

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Thanks for pointing me in the right direction. The information allowed me to determine which keys changed when disabling IEEE 802.x Authentication. However, I was not able to apply the information to solve my problem. I appreciate the assistance.

Rob WilliamsCommented:
Too bad you couldn't apply the reg changes. Thanks for the points Julie.

So it's two years after the fact, but it's still a relevant question.  The 802.1x authentication settings appear to be part of a service.  For wired connections, the service is called EAPHOST in XPSP2.  In XPSP3, another service was added, Wired AutoConfig.  The Wired AutoConfig service depends on the EAPHost service, but you have to have both started to make the checkbox appear.

Conversely, stopping these services makes the Authentication tab go away.  I'm not 100% sure whether this works for wireless, but it may.  Also not 100% sure on the behavior in Win2K.

well to be honest, I have conducted the same search myself and that is what got me here.
I hope my conclusions are good for anyone get to this point
