+ 0 Votes Did you solve this ? kjell.braten Updated - 7 years ago Hi, I am rolling out a solution with exactly the same unit (1242G) and experience the same problem. "station authentication failed". And nothing shows in the log files for ias or any other place on the 2003 server. If you found a solution please point me in the right direction here, i am banging my head into the wall....

I would disable any firewall just to help determine the real cause. + 0 Votes I'm in the same boat Leo 6 years ago Hi, I also read the guide several times now. I used to only use WEP so I wanted to look for a better way to secure my AP's with minimal user interaction required. Needless to say I cant get this PEAP to work. Maybe you can give me some suggestions becuase I dont even get any attemps logged into the Cisco AP event viewer. I'm pretty sure the problem lies in the AP config because the server side is was pretty easy to setup. I dont feel like there is anything happening between the AP and the windows2k3 RADIUS server. Do you know if I have to open any ports on the windows firewall? Thanks, Leo any suggestions would be appreciated. + 0 Votes PEAP authentication failed (Cisco 1200 vs Win2k3) dmmchowdary 6 years ago Hi, I have same problem. I think its the Win2k3.
