Pulling from some dusty mental archives, I recall something similar in our network: some refreshed Dell GX270 and some new GX620 models wouldn't authenticate, and never even prompted for credentials. We discovered the issue was related to the built-in Windows 7 drivers for their respective NICs. Upgrading to the latest version from Broadcom's website corrected the problem.
I hadn't seen any mention here of drivers, so thought I'd pass along my experience.

It also works if I have a machine that is in the domain and I check "Automatically use my Windows logon name and password". That will cover 90% of my cases. However, if a machine is not on the domain and connects I expect that I should be prompted by the supplicant to provide credentials. That is the part that is not working.

Just a thought. On 5/7/2013 6:31 PM, John Kaftan wrote: Actually it does work when I have that set. I tried that earlier today. Often in a university though machines are on the network that are not part of the AD domain, like the first two I was working with. Its crazy that Windows won't respond the the first eap packet from the switch unless credentials are configured to be provided automatically. Wireless prompts just fine. I did some research and it seems that 802.1x on wired is still unreliable. I found 7 patches to install and it still doesn't work right. I wonder why wireless is fine but wired isn't. The protocol has been around since 2002 or so. It should be fully baked by now.

Specifically look at section 1.1.10 - This would seem what “MIGHT” be missing ? How are you disconnecting and reconnecting from the network ? Are you unplugging the cable ? If you actually logout, you should get prompted for a new login. Best of luck !

I want to keep Admin-Edge. I do have 802.1x listed as first. 802.1x is working just fine if I store my credentials within the supplicate. My only problem is that I cannot get prompted by Windows.

Try setting 8021x as first in priority for authentication. I also have seen admin-edge enabled on the end system port (spantree) cause 8021x to fail also.

I have it working if I save my credentials in Windows. If I don't save my credentials Windows never prompts me for credentials. Packet captures suggest that the client never responds to the initial eap packet from the switch so the switch never sends the challenge. I have the Wired AutoConfig service running. Any ideas? I've been messing with all of the settings. I see this happening on two machines both of which do fine on wireless 802.1x. I am using B5s and NAC as my RADIUS server.
