I just saw that my former colleague (PFE) Tristan has posted an interesting note about the use of SetSPN “–A” vs SetSPN “–S”. I normally don’t repost other people’s content, but I thought this would be useful as there are a few SPN used in OpsMgr and it is not always easy to get them all right… and you can find a few tricks I was not aware of, by reading his post.
