Question

The target principal name is incorrect Cannot generate SSPI context

Answer 1

The 'Cannot generate SSPI context' error in SQL Server is related to authentication and can be resolved by checking the SPN configuration and authentication protocol.

Step-by-step explanation:

The error message 'The target principal name is incorrect Cannot generate SSPI context' is related to the SQL Server. SSPI stands for Security Support Provider Interface, which is a Microsoft Windows API used for authentication. This error typically occurs when there is an issue with the Service Principal Name (SPN) configuration or when there is a problem with the authentication protocol.

To resolve this error, you can try the following:

1. Ensure that the SPN is correctly configured for the SQL Server service account.
2. Verify the network connectivity between the client and the server.
3. Check if the client and server are both using the same authentication protocol (e.g., NTLM or Kerberos).

By taking these steps, you can address the 'Cannot generate SSPI context' error and ensure proper authentication in the SQL Server environment.
