The Service Principal Name(Delegation) Configuration has been set in correctly SPN Identity

Posted on by Microsoft Employee

Hi All

we are going through new Nav 2017 Implementation, and has setup the Application server & Data base server on the cloud which are part of our head office domain, when users try to access the application from their domain computers some time it gives the below error for some user at some point, after 5 or 10 minutes it works again 

"The service Principal Name(Delegation)" Configuration has been set incorrectly. server connect to URL : net.tcp://appserverip:portno/instancename/service. SPN identity servicename/appserverip:port no" Authentication failed on remote side(the stream might be still available for additional authentication attempt)

we use an AD account for NAV services, as per an online documents  i already registered SPN for the DB Server on the AD account, Do i need to register SPN on Application server as well .  any assistance is appreciated
