If a stand-alone CA, then you'll have to manually enroll and establish root trust of the certs. I'm assuming your stand-alone ca allows you to export the private keys, but it has been a very long time since I've messed around with stand-alone ca configurations. Enterprise CA is the way to go for a number of reasons-- That way you can copy and edit cert templates to ensure the certificate properties meet with your goals. You can also use Group Policy to automatically create machine certificates which are automatically trusted by the domain.

Yes the 2004 box is a member of the domain. For test purposes I've used a stand alone CA to generate the certificates. Is this allowed or does it have to be an enterprise CA and thus linked to Active Directory and Active Directory Users

The 2004 box is a member of the domain and thus trusts the root cert, right?

http://www.ISAserver.org

Trying to get certifiace based Eap authentication working for PPTP VPN
client
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.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.

Any ideas
