This content has been moved to Setspn. Be sure to use a version of Setspn.exe that is included with Windows Server 2008 or later because it includes the –S parameter for adding an SPN. Although you can use Setspn –A to add an SPN, you should use Setspn -S instead because -S will verify that there are no duplicate SPNs.
If you are using Windows Server 2003 or earlier, you will not be able to use the -S switch because it is not available for that platform. You can apply Microsoft Knowledge Base 970536 (https://support.microsoft.com/kb/970536) to Windows Server 2003 to get an updated version of SetSPN that does support the –S switch. In the case where you cannot use -S, you should manually verify that there are no duplicate SPNs by first running Setspn -L.
For more information about service principal names (SPNs) and using Setspn.exe to troubleshoot problems with SPNs, see Service Principal Names (SPNs) SetSPN Syntax (Setspn.exe).
