Hi, I got a problem with wireless single sign on in windows vista. Iam using PEAP with EAP-MSCHAP V2 to authenticate to 802.1x wireless then login to a domain using wireless SSO feature in windows vista. I have set SSO preLogonwith netsh wlan command. But the issue is that it works only with cached profiles. If a user login for the first time, shows error there are currently no logon servers available". Two scenarios working OK 1)Login with a cashed profile 2)Log off from a previously cached working profile and then login with a new user. Could someone help. thanks.

Hi, It seems that Single Sign-On is not successfully enabled. As a result, the user can logon only with their cached credential. To determine if a wireless profile has Single Sign-On enabled, you could check the wireless profile by using the command netsh wlan show profile name=ProfileName. Additionally, here is a Wireless Single Sign-On article for your reference: http://technet.microsoft.com/en-us/magazine/cc137762(TechNet.10).aspx Hope it helps.

Hi, Show profileshows sso=prelogon. But a logoff from working (cached) profile and login with a new user is possible. Any help? thanks

Hi I am also facing the same problem. How did you resolve it? Regards, Anil
