Re: IAS is not authenticating while using 802.1x

What EAP Method do you use ? EAP-TLS, PEAP ...
I also got this problem some time ago. But it was only temporary. After
few seconds the client tried again and then it worked.

If i am right the IAS must ask the DC if the machine account of the
authenticating client exists in Acitve directory. Maybe this
communication takes too long that the session times out ?
