SCOM Trick 13 – SPN

Service Principal Names (SPN) are used to uniquely identify an instance of a service. SCOM Services are also registered and mostly everything will be just fine, but in some cases you might have issues with this.
My friend Walter Eikenboom has written up a very good post about SCOM and SPN, how to check it, how to set it etc. Check it out here: http://systemcenterdynamics.wordpress.com/2009/08/26/scom-2007-r2-what-should-my-spn-registrations-look-like/
Also a post by Kevin Holman about the subject:

And another writeup by Jonathan Almquist:

Another case that can be brought back to an SPN issue by JC Hornbeck:
