I have posted a couple times regarding this issue, and so far, I have not been able to get this resolved.
I built a Windows 2003 x64 domain controller with Exchange 2007 installed on the DC. I also have Blackberry Professional Software installed on the DC. Neither the Windows or the Exchange server has been activated yet, waiting to get everything working first (do not know if that makes a difference in what works and doesn't work).
I am able to send an receive email with no problems. From the beginning I have not been able to access the internal OWA site or the external site. I will get the web page saying that there is a certificate error and when I select continue to the site I get a message of "Service Unavailable".
Nothing I have tried as worked and I am at the end of my rope with this. This is my first exchange build, I am in the process of working torwards my certifications and for the life of me I cannot get OWA to work.
The last thing I tried is adding the Network Service account permissions as seen in article http://support.microsoft.com/kb/842493
The other change that I made was previously I had a Windows Home Server running off the same domain name, that has since been changed and the only thing on this domain name is the exchange server.
Can anyone point me in the right direction or anyone live in Columbus, Ohio that could assist?
