PEAP failed with ACS3.3

Hi Sir,

I would like to find out is there anyone facing any problem when implementing PEAP using XP clients with ACS 3.3 and integrate with Microsoft AD to manage user database.

I have used ACS to generate self certificate and copy the .cer file and install it on client so that it is a Trusted Root CA inside the Xp client.

I have certain clients can be authenticated when Validate Server Certificate checkbox are checked. For other clients I need to uncheck the Validate Server Certificate checkbox, then they are authenticated. All are XP clients. There is incosistency in the configuration. WHat can I do next? Can anyone share any solution with me?

Thank you.

Delon

Re: PEAP failed with ACS3.3

We also had a problem with authenticating XP Clients using PEAP. Turns out there is a Windows Hotfix that solved the problem. Hopefully this will help.
