Problems with 802.1x,ACS and Windows Server 2000

Hi,

My components: ACS 3.3 running on a Server with Windows 2000 Server SP4 , 2950 Catalyst (AAA-Client) ,

Laptop with Windows XP SP2 (802.1x Client)

I have everything configured according to Cisco documentation, but I am getting one error in the ACS's log.( Failed Attempts active.csv)

Authen-Failure-Code : EAP-TLS or PEAP authentication failed during SSL handshake

I have a valide certificate on my Radius(ACS) server and about machine authentication I have a valide certificate on my laptop. (I have installed this certificate before i started to login at the 802.1x port of the switch)

Does anyone have any idea what the problem is?

Here is the Config of the Catalyst 2950 if that will help:

version 12.1

no service pad

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

!

hostname ACS-Client1

!

aaa new-model

aaa authentication dot1x default group radius

enable secret xxxx

ip subnet-zero

Did you get to solve this problem? I'm having the exact same problem.

Yes we get to solve this problem. Because it is a only a test senario, we installed everything new, win2000 server SP4,the certificate service and the winXP on the client.

The config of the switch is ok, we set the reauth-period and quiet-period to default.

Then we test the whole configuration with the IAS-Radius (MS). After this we install the ACS, following this document:(Certificates were already installed)

http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_configuration_example09186a00801df0ea.shtml

Attention, we used the AEGIS Client not the XP Client!
