Hello,

Customer network description: SBS2003 Std SP1. 2 NIC configuration. 2 CISCO Aironet Access Points. Wireless secure network configured as per Owen Williams whitepaper ( http://home.comcast.net/~clearviewtc/ ). 15 wireless clients (14 XP SP2 and one Vista) have been using this network without any issue for 2 years now.

We are adding to this network 4 new laptops. These laptops are Dell Latitude D531 (with Dell Wireless 1395 802.11 b/g). We have installed Vista SP1 from scratch on these systems along with the latest drivers from Dell. We have joined the systems to the domain and added them to a group called "Wireless Domain Computers". Thanks to that, upon reboot, the system do get certificates and wireless configuration. At that point it can connect to the secure wireless network. So far so good. But here comes the weird issue we're facing: we have switched on and off the wireless button on the laptop. Since we've done that, the computer does not connect to the wireless network anymore (even after several reboots).

When looking at the adapter in the network sharing centre, we do see the following message (approx. translation from French): "The parameters registered on this computer do not correspond to the required configuration for the network".

We have re-re-installed one of the computer, we have installed the latest network drivers, we have successfully tested the wireless card with a test (wep protected) wireless network.

I must admit that I am now clueless. Any hint, help or pointer would be highly appreciated.

Sounds like you need to delete out that Wireless network config for that specific configuation and set it up again.

I see that type of error when I've had a saved config for a Linksys and then I try to connect to another Linksys and the security settings are different.
