New Service on 3Tier Installation (2009R2)

yukon

Hi All,

We are planing to create new service instance (2009R2) on same Server and another server. Current installation type is 3tier installation. So we need to do the SPN and delegation for 3tier installation (normal installation). We will be use existing account (NAV service a/c) for new service instance and share the port on existing (NAV Server-1) and another server (NAV Server -2).

My question is do we need to do the SPN and Delegation for new service instance on existing server and new server? Can be duplicate SPN or what? :roll:

Best Regards,

Yes, you need to create a new SPN for the new services, as you cannot have two services on one machine with the same instancename. SPN's are created based on instancename, servername, portnumber and username. For more info: http://msdn.microsoft.com/en-us/library/dd301254.aspx.

Hi Poltergeist,

Thanks for your reply.
We will give different service instance name but we can use port sharing.

Now i'm confuse it. :?:

Sample SPN cmd. Is it right? How is port no?

setspn -A DynamicsNAV_1/NAVSERV.yourDomain.yourCompany.com:7046 yourDomain\yourUser
setspn -A DynamicsNAV_2/NAVSERV.yourDomain.yourCompany.com:7046 yourDomain\yourUser

7046 is the portnumber. If you want to do this, don't forget to use the NetTcpPortSharing service, and set dependency for that service...

Hi Poltergeist,

Thanks. I'll do the NetTcpPortSharing service.
