I am working for a small firm which is uses an XP/SBS 2003 backbone. Some of the users require off site access to their mail (exchange) and used webmail to do so. Unfortunately, there's a cert error. I think it's for two reasons.

Firstly, the cert is issued by the server, (adn therefore will never be recognised by any browser)

Secondly, the cert is set to the wrong url, (an internal one.)

I was wondering how you go about either changing the cert to the correct url or to repalce the cert with a new one.

Thanks in advance,
Chuck
