I have a client that we are migrating from a 2003 domain/Exchange 2003 to 2008 R2 / Exchange 2010. AD moved over, and all FSMO roles are pointing to new 2008 R2 DC. Exchange is showing the old 2003 DC as the DC it's using when I look under System Settings in EMC. I turned off the old 2003 dc and now Exchange will not come online. Keeps giving me an error when EMC is starting stating that the WinRM client received an HTTP server error status (500), but the remote service did not include any other info. When I look at services, the Edge Sync service is not started and will not start. It gives Error: 1053: The service did not respond to the start or control request in a timely fashion. These are all virtual servers, so I've even attempted to create a new Exchange server, but with no luck. Any assistance would be greatly appreciated.
