Win2k8 R2 RADIUS 802.1x PEAP with Windows XP SP3 RRS feed

  • Question

  • Hi,

    We have Win2k8 R2 NPS configured for RADIUS 802.1x authentication and client machines are running WinXP SP3. The RADIUS server is also the Certification Authority. The DC is a Windows 2003 Std machine. The certificate was already loaded on the testing xp machine, after we connect the cable for 802.1x and enter the username and password and domain on XP PC, the xp machine can't seem to get a DHCP address from the server.

    Upon checking the event logs from RADIUS server, there's always an event failure from security logs (NPS denied access to a user - Event 6273)

    Reason Code:      23
    Reason:            An error occurred during the Network Policy Server use of the Extensible Authentication Protocol (EAP). Check EAP log files for EAP errors.

    Not sure if there's misconfiguration or missing something here. Any help will be much appreciated. Thanks in advance!
