Question : Vista Wireless clients trying to Validate Certificates

We have a wireless network SSID setup for guest access that is for internet only.  Some clients work fine..mainly XP, but most vista laptops brought in try to validate the server cert even though this is unchecked on the wireless policy settings.

All wireless connections use PEAP and user authentication, as long as the laptop does NOT try to validate it works fine.  These machines are not domain machines and we do not wish to install a Root cert and enable validation since we are not requiring a validation for the policy for "Guest" SSID.

Has anyone else had this issue?

The IAS server is running on Windows 2003, and the LAN Manager auth reg hack has already been done.  Remember some vista clients work some just seem not to listen to what you tell them and keep trying to validate...

Thanks

Answer : Vista Wireless clients trying to Validate Certificates

Revisiting what you said, these are 'guests' accessing your wifi, and 'some' work, 'some' don't.

Since these are guests, there are other items to take into account. Each user's laptop will be unique. Everyone will have their own 'security' software and settings. In vista you'll have to 'trust' the network to get connected. If the users have Mcafee total protection, Norton Internet Security suite, etc, you more than likely have to allow or trust the network to surf.

Security Suites in conjunction with Vistas robust settings may make connection awry but easily resolved by configuring.

At the same time, not sure of your network scheme, but some versions of Vista won't do certain things, Like home basic cannot be added on network domains. I would make note of all Vista versions that cannot connect and see if they are all patched up (sp1, etc)

Hopefully can jog some ideas into your tiny dilemna. :)
