Have followed instructions in Toms books. Seems very straightforward. Have used a stand alone CA on a win 2000 server. Have put machine cert on ISa 2004 Configures ISA 2004 for Eap Done Eap user mapping Issued Cert to remote VPN win 2000 client All certs look OK but I get the following error messages in the isa2004 event log when I try and connect. The first message appears the first time I try and connect after a re-boot. Subsequent connection attempts always generate the second message. Message 1 Because no certificate has been configured for clients dialing in with EAP-TLS, a default certificate is being sent to user northgatevhnet\mark_wrightson_nmh. Please go to the user's Remote Access Policy and configure the Extensible Authentication Protocol (EAP). For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Message 2 The user mark_wrightson_nmh connected from 195.171.160.45 but failed an authentication attempt due to the following reason: A certification chain processed correctly, but one of the CA certificates is not trusted by the policy provider. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
