For help with this process, contact Active Directory product support, and mention this Microsoft Knowledge Base article. This may cause connectivity issues to the SQL Server instance. Assume that you have the following:. The SPN is removed from domain controller A but the change has not yet been replicated to domain controller B.
After some time, domain controller A replicates the deletion of the SPN from step 3 to domain controller B as part of Active Directory replication. The end result is that no valid SPN exists for the SQL instance in the domain and hence you see connection issues to the Sqlcluster instance. Verify the server environment Check some basic settings on the computer where SQL Server is installed:.
Kerberos authentication is not supported on Windows based computers that are running Windows Clustering unless you have applied Service Pack 3 or a later version to Windows For more information, click the following article number to view the article in the Microsoft Knowledge Base:.

Verify that the dates on the client and the server are valid. Here is my case. I had a remote machine that hosted SQL Server. I fixed it with the following:. Well initially it didn't but after waiting 2 minutes it did. I had this error- it happened because my password expired and I had to change it.
I didn't notice it, because in some programs I could still log in and everything would work normally including windows , but I couldn't log to any sql servers. In vb. If you still hit with error, remove the syntax completely. I can able to get this resolved by resetting the domain server machine, which is the domain server, but not related to SQL Server except domain managing followed by the client machines.
Had a really weird instance of this; All the web products that had connection strings containing the windows computer name of the SQL server worked fine, but the products that had a FQDN with the internal domain attached gave an SSPI error. Solution in this case was to set all the connection strings to the computer name only, removing the domain references. In case you are running a code not written in your computer, that runs in a computer used by your work peer, but not in yours, check the web.
Maybe there is your colleague's name as userPrincipalName at some place that should be in blank. That happens automatically when we create a service reference to the project in VS.
