Cannot generate SSPI context (Microsoft SQL Server) in SQL Server 2005

Wednesday, October 7, 2009 |

You might face error “Cannot generate SSPI context” while login to your SQL Server 2005 from SQL Server Management Studio. This is really annoying error. Basically the root cause of this error is current windows user doesn’t have proper permission.

This error occurs only when you are trying to login with “Windows Authentication”. You have two options.
1.)    Login with your SQL Server authentication, if you have id/pass
2.)    Set proper permission for your user.

As a simple option, you can right away switch to SQL Server Authentication. For digging more about permission issue of your windows user, have a look at some of the following link from Microsoft website.
