I really have no idea what you are talking about...
But... here is a guess


1) You can renew certificates on any Skew of Windows Server 2003, as long as
you have a valid certificate. This means that it is time valid, not revoked,
etc. If your revocation checking is not working, this could be the issue.

2) More inline.

Only enterprise CAs running on Enterprise Edition enable autoenrollment.
So, it really depends on whether the certificates are based on v1 or v2
certificates tempaltes.
I am not sure why you feel you have to:
1) Renew the subrodinate
2) AND then revoke all user and server certificates.

When you renew a CA, the previous certificate (if time valid) is still in
use and certificates signed by it are still valid.

Well, for OWA, you really should be purchasing a certificate from an
external vendor. It sounds like you have torn down your PKI and rebuilt. In
this case, you need to distribute the new root CA certificate of the chain
to all clients. The external IE 7 users are blocking the URL because the new
root CA is non-trusted.

certutil -addstore root "certfile" will fix that

This could help, but again, you really have provided no real information.
Trying to insult me does not work either. I am done with this thread

Brian,

I deleted all old certificates for the owa in both exchange and ISA. Then I
restarted exchange 2003, it still didn't work accessing OWA outside. Lastly,
I restarted ISA 2004, it worked now connecting outside.

You know I wish I have all the time to read all the books and articles but
I'm a network administrator on Linux, Unix, Windows, Mac, Blackberry, SMS,
ISA, Oracle, SQL, MOM, ESX, etc.

So this forum really help a lot and hope that you will answer us. I've
heard you on runas radio as well regarding the ev certificate on IE7.

I will look on the solution you gave me regarding renewing certificates on
2003 standard/enterprise automatically next year again because I have so many
things to do rather than recreating the scenario on my virtualization. My
certificates are good again for another year, yahoo or windowssssss
livvveeeeeeeee.

Thanks,
Ricky
