Connection to database causes SSPI context error I have migrated a SQL server from another server box that was decommissioned. They have the same name and also same IP address. However, when I connect to the server from an application using trusted connection, I get the &quot;SSPI context not generated&quot; error.
What I have done:

I have used the setspn -X to confirm there is no duplicate SPN.

I have changed the order of protocol to follow the order:
Shared Memory,
Named Pipes,
TCP/IP.

I have verified that when I restart SQL server, the service registers and deregisters. This was found in the SQL server log.

I have checked that on the SQL configuration the TCP/IP network protocol has the right IP and is active and enabled on both 32bit and 64bit.


I am running out of ideas and I am still getting the same error. I can't find any log that point to Kerberos.
Try using Microsoft Kerberos Configuration Manager for SQL Server to automatically detect and fix such SPN Issues:
