WLC/NPS 802.1x: Windows 10 can connect and Windows 7 can't

[Patrick Werner]

Hi Community.

We have a strange behavior. We setup 802.1x with Windows NPS. The Windows 10 can connect without an issue. But the Windows 7 clients can't connect some how.

I did a "debug client" on Win7 and Win10 (attached to this post), but i don't see any hint why Win7 can't connect.

Win 7 can connect with a PSK.

Does you guys find the hint?

Thanks and best regards Patrick

On the NPS server have a look into the Event Viewer -> Security tab. You should see the failed attempts there, including the reason why.
Also don't forget to update the client drivers if they use some 3+ years old ones.

That was a strange error on the NPS, we switch to another NPS with the same config and now ist working again.
