Hi M,

In all scenarios, unless we stated otherwise, all machines are members
of the same domain.

Thanks!

Subject: [isalist] VPN PPTP clients using EAP certificates

http://www.ISAserver.org

Trying to get certifiace based Eap authentication working for PPTP VPN
clients
on ISA 2004 from a windows 2000 professional PC. 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.

Any ideas
