SPN’s in Service Manager 2012


Hello,

Recently noticed a warning in the operations manager event viewer of our service manager management server.





Now you’ll normally only notice this warning upon a restart of the “System Center Data Access Service”. The warning will not occur upon a reboot of the server.

Same for the datawarehouse server.





Now we notice that our service is running under a specific credential.





While the warning states that the SPN for the machine account fails to register. This should normally be a bug. See http://social.technet.microsoft.com/Forums/systemcenter/en-US/5bc1c85a-1558-4ac3-8f07-412354e4b346/scom-2012-data-access-service-spn-not-registered?forum=operationsmanagergeneral.
This can be ignored.

Now let’s check the spn on the user account. The setup did not set the SPN’s automatically.

You need to manually add them using the setspn -a command



So you should have all service manager servers registered.
Check using setspn -l



Now I haven’t actually encountered some of the issues described in the following blog. But better save then sorrow.
