Hector, We had an issue with machine authentication when using wism and ACS V4.0 on Win 2003. The issue was when the domain controllers were rebooted, the machine authentication stopped working. We had to restarted ACS service to fix it. TAC identified it as a bug(CSCsd41569) in ACS V4.0 and it should be fixed in ACS v4.1. After we upgraded to ACS V4.1, the problem has gone away. Not sure why you see this problem with ACS V4.1... We use PEAP/WPA/WPA2 as well.

Here is our setup: -ACS v4.1 running on Win 2003 server, SP1 -ACS is only used for wireless -NAS: WiSMs running 4.1.185.0 -WLAN security settings: PEAP/WPA/TKIP We've been using machine authentication for a while with no issues up to now. I opened a TAC case, but as usual, they are slow and not very helpful. The only way we know that machine authentication has stopped working is when we get a call from our users. Nothing in ACS or the server gives us a clue as to what causes the issue. Restarting the ACS service fixes the problem. Any feedback will be appreciated.
