Trouble with Service Principal Name (SPN) - delegate access

  • I am working thru setting up a 3 tier application (client, mid-tier, db) with each tier on a separate system. When I go to setup the service delegation for the mid-tier the SQL Server Service "MSSQLSvc" is not listed in the "Add Services" box. I have verified in the SQL Server Log that the SPN is registered during startup. But an "SPN -L servername" does not list it.

    This is a Windows 2008 domain. All servers are running Windows 2008. I am using SQL Server 2008.

    This is an isolated testing environment and I am using the domain admin account to run the services. So I don't think this would be a permissions issue.

    Any ideas?

  • The SPN is going to be registered under the account running SQL Server - not the machine. Use the -Q option to query for the SPN record instead of -L. The -Q option allows for wildcards.

  • I had the feeling there was something simple that I was overlooking. That solved my issue. The setup notes were a bit misleading. Thanks for the help.

  • No problem - glad I could help.
