Microsoft Kerberos Configuration Manager for SQL Server


You can download “Microsoft Kerberos Configuration Manager for SQL Server” from here

Microsoft Kerberos Configuration Manager for SQL Server is a diagnostic tool that helps troubleshoot Kerberos related connectivity issues with SQL Server.

Kerberos authentication provides a highly secure method to authenticate client and server entities (security principals) on a network.  To use Kerberos authentication with SQL Server, a Service Principal Name (SPN) must be registered with Active Directory, which plays the role of the Key Distribution Center in a Windows domain.  In addition, many customers also enable delegation for multi tier applications using SQL Server.  In such a setup, it may be difficult to troubleshoot the connectivity problems with SQL Server when Kerberos authentication fails.

The Kerberos Configuration Manager for SQL Server is a diagnostic tool that helps troubleshoot Kerberos related connectivity issues with SQL Server.   It can perform the following functions:

  • Gather information on OS and Microsoft SQL Server instances installed on a server.
