I recently changed our domain name. I manually changed the DNS and now on Exchange 2010 on Server 2008 Standard is giving me an error. The error is when I attempt to do anything in the console... Federation Trust... Organization Relationship... Anything. Even when I try to access our domain /owa/, it gives me an error and says:
Outlook Web App didn't initialize. If the problem continues, please contact your helpdesk.Cannot find information about the local server XXX.XXXXXXXXX.org in Active Directory. This may be related to a change in the server name.
Ever since I did that, exchange is trying to connect to my old domain... DC1.OLDDOMAIN.COM instead of DC1.NEWDOMAIN.ORG

I just installed the exchange portion the other day and it hasn't been used yet. I was trying to change the domain prior to deploying it. Guess I'll just have to do an uninstall and reinstall to see if that does it.
Whenever I open up the Exchange Management Console, it says 'Unable to find 'DC1.OLDDOMAIN.COM' computer information in the domain controller 'DC1.OLDDOMAIN.COM' to perform suitability check. Verify the fully qualified domain name. It was running the command 'Get-OrganizationConfig'.
That error is whats showing it is pointing to the old domain controller, not the new one, DC1.NEWDOMAIN.ORG.
So I followed those directions (http://msgsense.com/2011/01/18/manually-uninstall-last-exchange-2010-server-from-organization/) to remove it manually and it was successful. Now, when I go to reinstall it, it keeps failing at the Language Files with the error "Unable to remove product with code dedffb64-42ec-4e26-0401-430e86df378c. Fatal error during installation. Error code is 1603. Last error reported by the MSI package is 'Could not open key: UNKNOWN\Components\E8801C2D248F4094FB915079D7FC0B09\46BFFDEDCE2462E4401034E068FD73C8.

It was running the command 'Uninstall-MsiPackage -LogFile 'C:\ExchangeSetupLogs\Uninstall.ar.Client.20110319-130923.msilog' -ProductCode 'dedffb64-42ec-4e26-0401-430e86df378c".
