Hello MVP,

I am setting up a Wireless Network and trying to take advantage of
IAS with EAP-TLS in Windows Server 2003. The client is prompted for a
cert but when I select the cert it just tries and tries then prompts
me again. This continues....
I have a linksys wrk54g using WPA - Radius. I have both user certs and
computer certs on the client. I have a computer cert on the IAS
server. Auto entrollment is working as it should.

Note: I am using L2TP/IPsec successfully over the same Windows
system. Also note that currently I am having to just use WEP which
hopefully is just temporary.

Any help would be greatly apprciated.

I just did this recently using a Cisco Aironet 1231 and it's still pretty
fresh in my mind. I didn't use WEP, not necessary since I used WPA and
TKIP.Works great.

I'm assuming you used a Windows 2003 Enterprise for the CA to give you the
ability to duplicate the User and Computer certs to create your
autoenrollment certs, and in the certs, you are allowing user and computer
certs to login.

From what you've posted, if you've verified by checking the workstation
(certifcates snap-in) that it has received a cert thru autoenrollment, and
depending on how the clients wireless interfaces are setup, whether static
settings or controlling the clients thru a GPO, it should pretty much work.

Are you using a GPO for a wireless policy? If so, what do you have set in
there as far as the client settings (WPA, WEP, SSID, etc)?

Is the key length on the CA and the certs no larger than 1024? Cisco, and
what I understand many others, do not support keys larger than 1024. If it
keeps prompting you for the cert, than that may be a better guess as to why
this is happening.

Make sure your RADIUS Linksys client and IAS server shared secrets match.
(You'd be suprised how this one can be easily overlooked).

Did you create an IAS policy to allow 802.1?
Controlling access by groups in the IAS policy? If so, are the users part of
that group?

What do the ISA logs, ISA server and client Event viewer logs, and possibly
the Linksys logs say? Any errors on the Event logs on the CA?

Sorry for all the questions, too many places this can go wrong, and need to
narrow it down.
