Security Support Provider Interface (SSPI) is a set of Windows APIs that allows for delegation and mutual authentication over any generic data transport layer, such as TCP/IP sockets. Therefore, SSPI allows for a computer that is running a Windows operating system to securely delegate a user security token from one computer to another over any transport layer that can transmit raw bytes of data.

The "Cannot generate SSPI context" error is generated when SSPI uses Kerberos authentication to delegate over TCP/IP and Kerberos authentication cannot complete the necessary operations to successfully delegate the user security token to the destination computer that is running SQL Server.

For additional information as to why the Kerberos operations cannot be completed, select option "Troubleshooting authentication failures due to Kerberos issues " at the bottom to review and implement the steps.
