Consider the following scenario:
- You install Microsoft SQL Server 2008 on a computer that is running Windows Server 2008 R2 or Windows 7.Â
- You enable the FILESTREAM feature in SQL Server 2008.
- You run an ADO.NET Framework application to remotely perform read or write operations on FILESTREAM data in SQL Server 2008.
- You run these operations from a computer that is not running Windows Server 2008 R2 or not running Windows 7.
In this scenario, you receive the following error message:
Either a required impersonation level was not provided, or the provided impersonation level is invalid.
This problem does not occur when you run the same operations from a computer that is running Windows Server 2008 R2 or that is running Windows 7.
