Hello Everyone,I am having problems with setting up a wirelless networking on a Vista Business laptop. Our Wireless network here at work requires certificates to be installed. One is the user certificate, and anohter is a Trust Root CA Certificate. I've installed both of them and they do show up in the Certificate Manager in the proper locations. We are using WPA Enterprise Security type with TKIP Encryption. And then our IAS Server validates the certificate becofore the user gets on the wireless.The problem I am having is this, even though all certificates are installed and the wireless adapter is configured with the same options as XP clients that successfuly connect, everytime It tries to connect, I see a notification message at the bottom of the screen saying "A Certificate is required to connect to 'SSIDNAME' ". So it seems to me that Vista does not see the certificates, maybe the aren't installed properly, but they do show up in Certificate Manager. I am lost, could anyone point me in the right direction?Thank you!

Did you ever get this figured out? I just purchased a few Vista licenses to test out and getting the certificate installed was a major task of its own. Now Vista isn't seeing the thing. I'm pretty tried right now so I'll keep this short so I don't get banned. We have gone from a few clicks to this. Thanks for any help. PLW

Almost a year later and I've just encountered the exact same problem. My scenario is a user on Vista Business had a certificate that expired, so I gave him a new certificate and now I'm just getting the faithful old "A Certificate is required to connect to ..." Any resolution?

So is there any word on this? I'm attempting to install a new 802.1x/Radius/PEAP network and keep getting this exact same result from my Vista laptop. Group policy mandates auto-enrollment, and the settings seem to be fine... I'd really like to find/issue this certificate so we can get our network operational... Sad that in all this time, nobody from MS has weighed in on this...

Resurrecting this thread - did anyone get to the bottom of this? We have had our WLAN setup for a while not, XP laptops work a treat, but are upgrading to Windows 7 and am experiencing this issue. Have tried with Vista, same again - only XP works.... Any advice of this would be appreciated. Thank you.
