I am working at company IT department. We are hosting our own exchange 2003 server as our primary mail server. Exchange 2003 server is running with windows 2003 enterprise. Staffs are using outlook 2010 and starting receiving the security alert message regarding autodiscovery.domain name, there are 3 statements on security alert message, 2 of them have checked "Green", and the 3rd one has RED corss saying the name of certificate is invalid or does not match the name of site.
Our DNS hosting is network solution, I called them, they asked to purchase NS Protect SSL basic for autodiscovery.domain name, and they also asked me to create a new CSR on exchange 2003 and put this new CSR to network solution in order to obtain a validated CA from network solution and then install it to our exchange server 2003 to fix autodiscovery problem.
I think this is our internal problem, and Exchange 2003 does not have autodiscovery service, there must be a way to disable or fix outlook 2007/2010 autodiscovery issue.
I have spent $399.00 to purchase NS protect SSL(basic) from network solution, I do not know whether it is the right solution. If we can solve this problem internally, we do not need to spend $399.00 to do this from network solution. I need to your helps.
I don't even know how to get a new CSR on Exchange 2003.
Please help us, Thank you, Paul
