FIX: Error message when you try to edit the connection manager for a migrated package in SQL Server 2005: "The specified provider is not supported"

Consider the following scenario. You migrate a Microsoft SQL Server 2000 Data Transformation Services (DTS) package to a SQL Server 2005 Integration Services (SSIS) package. You open the migrated package by using Business Intelligence Development Studio, and then try to edit the connection manager for the SSIS package. In this scenario, you receive the following error message:Note You can execute the migrated package correctly. No data loss or data corruption occurs.

This problem occurs when you migrate a DTS package that contains ODBC connections, and the SQL Server 2005 Package Migration Wizard migrates ODBC connections to use the native ODBC provider.

To resolve this problem, obtain the latest service pack for SQL Server 2005. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

You can execute the package correctly. However, if you want to edit the connection manager in Business Intelligence Development Studio, you must delete the connection manager, and then manually create a new connection manager for the migrated package.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
This problem was first corrected in SQL Server 2005 Service Pack 1.
