When you install the Microsoft Dynamics CRM 4.0 server, you receive the following error message:
Microsoft.Crm.CrmArgumentException: Invalid domain name. Domain name is either invalid or unreachable.
This problem occurs if the domain controllers in the domain or in the forest in which you install the Microsoft Dynamics CRM 4.0 server are unreachable.
The domain controllers may be unreachable if the domain controllers are closed or if a network problem exists.
This problem also occurs in a Windows Server 2008 domain if the following conditions are true:
- The Windows Server 2008 domain contains a read-only domain controller.
- The Setup program finds the read-only domain controller first.
This problem is fixed in the latest cumulative update rollup for Microsoft Dynamics CRM 4.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
