Laptops unable to connect to wireless

[Kent_Sapp]

Our school district's Windows 7 laptops are unable to connect to the wireless with the "validate server certificate" setting enabled under the wireless properties. If I uncheck that box the laptop is able to connect. With about 1000 laptops unchecking that on all will be a pain. Would adding a certificate to the NAC solve this problem?

You'll need to either deploy the CA certificate to the clients trusted certificate store or uncheck the validate server certificate box, which I think can be done via Group Policy definition.

The problem seems to be that the client can't match the server certificate as a trusted one, this is why it works when the client is told not to validate the server certificate it works.

Yes, that is correct.

Hi Kent,

as it isn't clear from your post my assumption is that ...

The Win7 laptop is connected to a SSID which is using 802.1X PEAP and is authenticated via the NAC which has a conenction to a databse (i.e. LDAP) to check the accounts.

Correct ? If not please let us know how the systems interwork which each other.
