Had to rebuild an installation of SBS 2008 after Active Directory became corrupted. Rebuild went smoothly. However, the client running Windows 8.1 that was connected to the old build will not connect to the server when I run http://connect
or Launcher.exe from the client. I get error 500 internal issue with the server. The client seems to be connected to the domain because I have Internet access. After logging on after the rebuild, Outlook gave me a choice of using a temporary mailbox or the old data. Using old data would not allow Outlook to open, but using the temporary mailbox opened Outlook and loaded mail from the Exchange server but the connection to the server was intermittent. Changing the Outlook profile stabilized the connection between Outlook and Exchange 2007. At least Outlook says it's connected but no mail comes through. The client pings the server without a problem. I installed the certificates from Register.com I had on hand, but they have expired, and I've ordered new ones. Consequently, I continue to get warnings about expired certificates.
