I have a stable and working Exchange 2003 environment and am now working on moving over to Exchange 2010. I have installed a second server (Windows 2008 Standard SP2) and properly integrated it into the Windows 2003 domain. I have the Forest and Domain level at 2003 and the Exchange server in native 2003 mode.
I have proceeded to updating the schema and have been stuck at the /prepareAD step. I get the following error:
Configuring Microsoft Exchange Server
Organization Preparation ......................... FAILED
The following error was generated when "$error.Clear(); install-RootOrganiz
ationContainer -DomainController $RoleDomainController" was run: "Couldn't find
the Enterprise Organization container.".
I have check everything and cannot figure out the source of the "Couldn't find the Enterprise Organization container" error. DNS appears correct, the Forest/Domain is set properly and the 2008 Server appears to be integrated in the AD domain correctly.
Any help of suggestions?
