When we implement CRM 2011 we always hear or read the term Service Principal Name (SPN) for accurate Kerberos Authentication; however, sometimes understanding Kerberos Authentication is time consuming and needs experience.

Sean has written a detailed blog explaining Kerberos Authentication here.

Identifying the right SPNs can be daunting and it would be really nice if we had a simpler way to identify them.  To make SPN identification easier I have put together an excel workbook which could help us generate a list for different deployment schemes.  The Workbook has different sheets covering most common scenarios like Single Server Deployment and Split Server Deployments. (see attached worksheet below)

Please feel free to post your feedback to improve the workbook so we can accommodate more deployment scenarios.
