One is “Cannot generate SSPI context” and the other is “SSPI Handshake Failed”. The first error is commonly because the client is trying error 17806 severity 20 state 14. in sql server 2008 r2 a Kerberos authentication and that failed, but it did not fall back to NTLM. The second one happens usually when the user is not authenticated. So I looked into the SQL Server Security Event Logs and I can see this entry:

The best link was this one: http://sqlcan.wordpress.com/tag/sql-error-17806/ It describes a specific situation that the author had, and how eventually resolved after having tried both this and that. His solution is necessarily not your. The root problem is that SQL Server and the AD are not on terms with each other about the login. If you had the configuration working in the past, you should review what changes that have occurred in the domain recently. If you are not adminstering the AD yourself, you will need to talk to the Windows administrators.

I have not yet found a solution. The best advice I've heard so far is "something is wrong with AD". –epic_fil Oct 4 '12 at 22:04 This error happens 100% of the time if you try to log in the SQL Server with integrated security but your current security context is from another domain (not trusted) or logged locally on the client machine. –wqw Sep 16 '13 at 14:12 add a comment| 3 Answers 3 active oldest votes up vote 16 down vote The key to this issue, for me at least, is the fact that the connection to SQL Server is being made over the loopback interface (127.0.0.1). I had the same symptoms, and found the answer in this blog post. To summarise: there is a loopback check taking place which causes trusted connections via the loopback adapter to fail. This check can be removed by adding a registry entry as follows: Edit the registry using regedit.

There were various messages listed out on forums, etc., but for me we found that the error was originating because we have DNS issues and Domain Controllers (DC) was unreachable due to a network switch configuration problem. So if you see these errors, you may see in the EventLog a NetLogon error relating to not being able to reach a domain controller to login, and you will get the error below because the DC is the one that hands the Kerberos token to the process for use in SSPI related activities.
