Ned here again. Are you using MS Dynamics CRM? Be sure to check this excellent blog post from our colleagues Jeremy Morlock and Henning Petersen on how CRM uses Service Principal Names and what you need to get it all working:

http://blogs.msdn.com/crm/archive/2009/08/06/configuring-service-principal-names.aspx

It covers the following scenarios, step by step:

  • Host header added to site
  • Change CRM Application Pool to run as Domain User
  • Change CRM Application Pool to run as Domain User when other application pools run under separate domain user accounts

Nice work guys!
