I am setting up WLAN to secure our wireless network.  I plan to use 802.1x
EAP/TLS with certificates for the client machine and user.  My issuing
certificate server is Windows 2003 Enterprise and I have the certificates set
to Autoenroll the machines in the correct AD group.  WHen I check the
machines, they appear to have the correct certificates installed.  The AP is
set for 802.1x and is pointed to the radius server.  The radius server has
the AP as a client.  However, when trying to connect to the AP, I get a
"Windows was unable to log you into the network" error after the initial
connection to the AP.  Ipconfig shows an ip address of 0.0.0.0.  I need some
help troubleshooting this issue.  I've included some of the radius server log
below but I don't see any obvious problems.

I am really scratching my head on how to tell where the process is failing
so any help would be greatly appreciated.
