We are seeing wired 802.1x authentication failures on some new laptops. Here is the event that is generated when the authentication failure occurs:

Log Name: Security
Source: Microsoft-Windows-Security-Auditing
Date: 3/1/2012 3:23:27 PM
Event ID: 5633
Task Category: Other Logon/Logoff Events
Level: Information
Keywords: Audit Failure
User: N/A
Computer: %COMPUTERNAME%
Description:
A request was made to authenticate to a wired network.

Subject:
Security ID: host/%FQDN%
Account Name: -
Account Domain: -
Logon ID: 0x0

Interface:
Name: Intel(R) 82577LM Gigabit Network Connection

Additional Information
Reason Code: Explicit Eap failure received (0x50005)
Error Code: 0x34d

Machine is connected directly to the port and does not connect through a VoIP phone. Any thoughts as to why this is happening?

Hi,

Look for more informatipn en event viewer.
Critical EapHost messages are logged under: “Custom Views\Administrative Events”
Non-critical messages are logged under: “Applications and Services\Microsoft\Windows\EapHost

"Analytic" and "Debug" type event messages can be seen under the same path by selecting Show Analytic and Debug Logs from the view menu in the title bar.

Regards
