Windows 10 ACS issues

[ahcadmin1]

Hey all,

I cannot get Windows 10 machines to authenticate against our ACS.  I get the message: "Unexpectedly received empty TLS message; treating as a rejection by the client"

Wifi settings on our computers are set to NOT use a server certificate.  All other settings are the same for Win 7, which works fine.  Anyone else have/had this issue?

Thanks

Josh

I assume you are using PEAP authentication?

Can you see the ACS certificate (or the root CA that issued the ACS certificate) on one of the Windows 10 machines?  If you double click on the certificate does it report that it is valid?

Has the Windows 10 machine definitely got the correct time on it?

Where would I find the ACS cert?

Yes time is correct, just verified.  I also would like to add that this is for several Windows 10 devices, my laptop being one and the others are Surface Pro 3's.
