Yesterday I was working with a couple of my technicians in Schrock Innovations' Lincoln Service Center, and we started noticing a problem with the adapters in the notebook computers on the bench.

One by one each notebook's wireless network adapter stopped working. We were getting the following error from the Windows Zero Configuration Service :

Windows is unable to find a certificate to log you on to the network [Network name here]

After comparing our notes on the three separate units, we realized we had all just installed Windows XP Service Pack 3 before the problem occurred.

We went into the properties for the network adapter and turned off the 802.11x Authentication (the source of the error) which was somehow turned on by Service Pack 3 as far as we could tell. But after rebooting the computer the authentication would turn its self back on every time.

After some trial and error, we developed a procedure to resolve the issue. Leave me a comment if this has been helpful to you.
