Hello,

I was hoping someone could help a newbie out. I have recently setup a cisco wireless solution 2 4402 controllers and the cisco ACS running on W2K3 Server. Dual Core processors 8gb of mem. We have about 78 1242 lwap. Clients are authenticating (using external db active dir) by machine name then username. We are using PEAP WPA TKIP and WPA2 AES. Everything has been working GREAT for several months. Over the past several days authentication has stopped several times. The one time all of the radius services were stopped. Could not start them manually, but a reboot cleared the problem. Second time all services appeared to be running but no authentication. A reboot solved the problem. These are 2 errors I noticed in the services monitor reports

"Test Timed out for service: CSRadius. Test Timed out for service: CSTacacs."

"Auth server down: Could not change Password"

Any help or pointers would be greatly appreciated.

Thanks you

I have this problem too.

These errors are seen when the radius server are down or are not responding. Check the configuration on the RADIUS server. Also, post the configuration of the WLC so that we can ensure things are ok on the controller side.
