SSPI is the short form for the Security Support Provider Interface. It is a collection of MS Windows API. It enables authentication of TCP/IP sockets which are data transport layers in networking. In simple terms, when transferring data from one computer to another over TCP/IP, SSPI issues a security token. This will ensure the secure transmission of data between the sending and receiving devices. Sometimes, the SSPI assigns a security token for the receiving device by using Kerberos authentication. If Kerberos cannot assign the token properly, then we get to see the cannot generate SSPI context error.
When this error occurs, the connection to the SQL server fails. A message will generate that says “Connection failed Cannot connect”. In this guide, I will explain to you how to fix this issue. There are a few workarounds that ideally should solve the error. Let’s check them out.
Troubleshoot: “Cannot Generate SSPI Context” Error (SQL Server)
Here is the various workaround that you can try to fix the cannot generate SSPI context error.
