While setting up Exchange Server 2010 on Windows Server 2008 R2 Enterprise [which has SQL Server 2008 R2 Enterprise (upgrade from SQLExpress 2008) and SharePoint Server 2010 Enterprise for Partners (an upgrade from Foundation 2010) installed already], in setting the Deployment Configuation I selected Create New Domain in New Forest and now I get this message when trying to access eeecoop.com: "Cannot connect to the configuration database" and also the Remote Desktop Connection now gives me a "Login attempt error" everytime I try. I think the problem is that I set the "New Domain for New Forest" to corp.eeecoop.com and I should have selected instead gone for "Add domain controller to existing domain". I'm not sure what to do next. Please help. tnx

Thanks for the reply Gulab. So, it would have been best if I setup each server on a separate virtual server using Hyper V? Also, when I select existing domain should then setup a new subdomain or just using the same existing domain (i.e. eeecoop.com verse exchange.eeecoop.com) Problem is I can't get into the server via RDC. Is there any way round this, i.e. to get into the server not via RDC or directly? Thanks for the help

Hi - managed to login to corp.eeecoop.com and then my host managed to switch back to eeecoop.com So it was resolved. Thanks!
