Hi, I am trying setup a Vista client and a Longhorn server to do NAP health checking in PEAP authentication. In my CRP I have overdridden RAP authentication, enabled peap and enabled quarantine checks. If in the client, I uncheck enable quarantine checks in the PEAP settings and authenticate, it completes successully albeit in the IASNAP.txt log file I see the warning [3540] 11-15 16:12:28:215: WARNING: No SHV Session Handle On my client EAP QEC is enabled, NAP Agent service is running, and Windows Security Center is turned ON. If I enable qurantine check in the PEAP setting in the client, the authentication fails and this is what I see in the IASSAM.txt 3540] 11-15 16:21:08:843: Successfully validated windows account DEMO\bob. [3540] 11-15 16:21:08:843: Successfully validate PEAP inner identity [3540] 11-15 16:21:08:843: Processing output from EAP: action:1 [3540] 11-15 16:21:08:843: Inserting outbound EAP-Message of length 59.

Thanks - Rajesh.

wanted to add that the Longhorn version is Build 5384

to close the loop .. everything works fine with Longhorn build 5600
