Beaware of:
· SQL Server 2005, Workgroup Edition is supported only if Microsoft Dynamics CRM is installed on Windows Small Business Server.
· SQL Server 2005, Workgroup Edition is not supported for running the Microsoft Dynamics CRM Connector for Microsoft SQL Server Reporting Services when Microsoft Dynamics CRM Server is installed as an Internet-facing deployment (IFD). This is because SQL Server 2005 Workgroup Edition does not support custom data extensions. Therefore, some features such as report scheduling will not work.
