Create Service Principal Names
- Create a Service Principle Name (SPN) for each web application that needs to be shared as follows:setspn –S HTTP/SPHOST:PORT <domain>\AppPoolUser setspn –S HTTP/SPHOST.FQDN:PORT <domain>\AppPoolUser setspn –S HTTP/SPHOST <domain>\AppPoolUser setspn –S HTTP/SPHOST.FQDN <domain>\AppPoolUserIf the port is a default port, such as 80 or 443, omit the commands that include port above.Some of the lines only require a host name while others require a fully qualified host name. If the application pool identity is for a built-in user such as Network Service, then specify the host name as shown below instead of <domain>\AppPoolUser.setspn –S HTTP/SPHOST:PORT <domain>\SPHOST setspn –S HTTP/SPHOST.FQDN:PORT <domain>\SPHOST setspn –S HTTP/SPHOST <domain>\SPHOST setspn –S HTTP/SPHOST.FQDN <domain>\SPHOSTIf you use SSL, the SPN must refer to HTTP instead of HTTPS.
