You cannot use a custom application that uses a separate application pool in Microsoft Dynamics CRM 3.0 Professional Edition for Service Providers

You cannot use a custom application that uses a separate application pool on a computer that has Microsoft Dynamics CRM 3.0 Professional Edition for Service Providers installed.

You may experience this problem when you try to access the custom application. When this problem occurs, you see the Microsoft Dynamics CRM 3.0 Professional Edition for Service Providers logon window instead of the custom application logon window.

This problem occurs if you use Microsoft Dynamics CRM 3.0 Professional Edition for Service Providers together with Microsoft SQL Reporting Services 2005.

This problem also occurs if you use Microsoft Dynamics CRM 3.0 Professional Edition for Service Providers together with any other custom Microsoft CRM Software Development Kit (SDK) application that has the following conditions:

• The custom application requires a separate Microsoft CRM application pool (CRMAppPool).
• The required application pool is not the default application pool that is used by the Microsoft CRM Web site.

Note Microsoft .NET 2.0 applications must be set up on a separate application pool because Microsoft CRM Dynamics 3.0 is a .NET 1.1 application. Microsoft .NET 1.1 applications and Microsoft .NET 2.0 applications cannot share the same application pool.
