Sometimes users get the message attempting to authenticate.

We are using a Wireless Security Switch, with accesspoints connected to it. behalve that there is a IAS server and a Certificate server.
Users do get the certificaat per policy. The problem occurs in a lot of differernt locations of our company. Even microsoft doesn't have a solution for this. I was able to reproduce the problem today  twice.
First time when I changed the roam time of my wirelless NIC card in the laptop. The second time when i walked trom the 4th floor to the 5th floor.

The roam time was changed from 45 seconds to 5 seconds and also to 5 seconds to see the difference.

1) make sure you have the latest software and firmware for the switches/ APs and anything associated with this.

Also consider using packet sniffer to get more info


I hope this helps !

The solution couldn't be found in the network, but it was more a client related issue.
Currently the problem appears not to all the users, but only to a couple.
