802.1x Radius Problems

[S Sainsbury]

I have built a new Windows 2003 IAS server and configured Wireless
Authentication (802.1X).

I followed the TechNet documentation "Securing Wireless LANs with
Certificate Services".

I have a test laptop which has a Wireless Group Policy applied, I confirmed
the wireless policy settings are applied to the laptop, the user and computer
certificates were enrolled and installed.

A Linksys WRT300N has been configured as the Wireless Access Point and has
the relevent Radius server settings applied.

The problem is that the laptop attempts to connect to the Access Point, it
connects and then within seconds it disconnects, it attempts a reconnect
several times but then gives up. There are no obvious errors showing in the
event viewer, there are a couple of EAPOL 2002 and RegSrv Events but nothing
else.

I checked the logs on the IAS server and it shows the user/computer as
requesting access and access being granted, no errors appear in the IAS or
Event Logs.

I have tried several different laptops and two different Linksys access
points, I have also reapplied many of the configuration settings on IAS but
still the same.

from what I can see the IAS, Root CA and Group Policy are all working fine,
im assuming the issue is either the Access Point or the Client.

Can anyone help?

RE: 802.1x Radius Problems

Everytime I get to the point of desperation and post a problem on this
newsgroup I end up fixing the problem myself 5 minutes later!

It was down to the Access Point, the security settings on the Linksys
WRT300N were set to "RADIUS" which common sense would suggest is correct, but
no, so I set it to PSK-Enterprise and TKIP. Updated the Group wireless
Policy to match and hey presto!
