Is it simply not sent, or somehow not available? Because I know for sure
that there is a cert on the client. And I did nothing else, than on the
other machines where it works since 2 weeks.
Just to make it explicit: I create a user-cert in TinyCA2(linux). I
export the cert as a p12 and include the key and the CA into that p12
container. I also disable the passphrase. I put that file on the network
where the client can find it.
On the client I open the MMC as local admin and include the Snap-In
Certificates for Local-Computers. Then I import the created cert into
My-Certificates and copy the CA-Cert into the "trusted certification
centers" tree (it's in german). It worked for another 2 W2K PCs and for
four XP-Pro-SP2 PCs.
The APs are Linksys Switches and they do what they should.

I use EAP-TLS for machine-authentication (In Windows the "Smartcard or
Certificate" Authentification).

Because if I do only a machine-authentication, every machine which has a
valid cert can connect to the network.
If I write the explicit hostname in the users file, I have more control
over the single clients connecting. If they are not in the list, they're
not allowed to connect, regardless if they have a valid cert or not. I
think it could be done more elegant using crls, but I'am not yet at this
point. I try to understand why one PC can connect and the other one can
not, although I did the same procedure.
Thanks for your help
Alex
