W2K doesn't ask FreeRadius with EAP

[Alexandros Gougousoudis]

Hi,

I got a very strange problem and I don't know where to look else. Maybe 
one of you have an idea what could be wrong.

I've setup (with a lot of the lists help) a Freeradius server, based on 
certificated, doing a machine authentification over our linksys switch 
as AP. The clients are using EAP-TLS and for the most clients it works. 
But there are two W2K clients which doesn't want to register over 
radius, the radius server even doesn't get a request.

I took a freshinstall W2K with SP4, put on all updated, put on IE6 and 
the necessary certs and registry patch, started the wireless service, 
configured network settings, rebooted. If I connect the networkcable to 
secured ethernet port I get in Windows "Couldn't logon to the network" 
(in german). I have 2 other W2K machine working without a problem (even 
on the same Switch port).

I had a Realtek NIC in that PC, put on new drivers, no effect. Put in an 
older 3com NIC, no effect. It's like the AP doesn't forward the request 
to the Freeradius server. With other W2K no problem, with XP no problem 
with this AP.

Something I could do, beside throw the pc out of the window?

TIA
  Alex
