Our application is using Filestream columns to hold images in the database. The application runs perfectly on the desktops using windows 7 but gives a exception on the Windows XP machines. The following exception is thrown:
"Either a required impersonation level was not provided, or the provided impersonation level is invalid."
I have tested several accounts on both the Windows XP en Windows 7 workstations but all refuse to work on the XP machines. The database is SQLServer 2008R2 running on a Server 2008R2. All clients and the server are part of the same domain.
