Problem with SSTP VPN conection when PEAP selected on Windows Server 2008 RRS feed

  • Question

  • I am configuring SSTP VPN server with NPS and cannot make PEAP works.

    I cannot connect with PEAP, but I can connect when switch back to EAP-MSCHAP v2.

    The error message on client when I try PEAP is:

    Error 812: The connection was prevented because of policy configured on RAS/VPN server. Specifically, the authentication method used by the server to verify username and password may not match the authentication method configured in your connection profile.

    I used clients with Windows 7 and Vista.

    I can use EAP-MSCHAP if it is the only Network Policy Authentication Method or it is set as first EAP Types before PEAP. If PEAP is before EAP-MSCHAP the same error happen even if client is configured to use EAP-MSCHAP not PEAP.

    The following events error are created on server:

    5061 System Integrity

    6274 Network Policy Server
    (Network Policy Server discarded the request ... Reason: An internal error occurred)

    20255 RemoteAccess
    (The connection was prevented because of a policy)
