SYMPTOMS
When you upgrade Microsoft Dynamics CRM 3.0 to Microsoft Dynamics CRM 4.0, you may receive the following error message:

The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

You receive this error message in the Environmental Diagnostic Wizard. This error message is related to communication problems with the domain controller.

Then, you try to correct the communication problems with the domain controller. However, you do not exit the Microsoft Dynamics CRM setup process. Instead, you click Back in the Environmental Diagnostic Wizard. Then, you click the Next button. You receive the following error message:

Data ServerInstallInfo.OUDistinguishedName is not available.



CAUSE
This problem occurs because the setup process keeps the information in Active Directory from the previous failed Environmental Diagnostic Wizard check. This occurs even though the check in Active Directory passes on later verifications.



RESOLUTION
To resolve this problem, follow these steps:
 * 1) Close the Setup Wizard to cancel out of the upgrade process.
 * 2) Check problems in Active Directory, and then resolve any problem in Active Directory.
 * 3) Open the Setup Wizard to restart the Microsoft Dynamics CRM 4.0 upgrade.
