Dynamics Navision 2009- Second Instance Service wont start.
Posted on 2013-01-24
I am not a Navision pro by any means so there may be some back forth in order to give you the whole picture.
Our consultants have installed a second instance of Navision on the same server in order to run a test bed simultaneously as the live. The live service starts fine, but the second service kicks up this error when trying to be started:
The Microsoft Dyanmics NAV Server instance 2 (which is the name of the 2nd service) on local computer started and then stopped. SOme Services stop automatically if they are not in use by other services or programs.
The consultant asked me to do the below article which I have no idea???
Can someone help?
Create Service Principal Names
The first step in setting up delegation is to create service principal names (SPN). To make delegation more secure, Active Directory uses Kerberos to authenticate services. An SPN is the name by which a client uniquely identifies an instance of a service, using the account under which the service runs. You must create one SPN for the Microsoft Dynamics NAV Server service and one SPN for the SQL Server service to make delegation work.
To create service principal names
1. Open an elevated command prompt. To do this, click Start, and then in the search window, type Command Prompt. Right-click Command Prompt, and then click Run as administrator.
2. At the command prompt, create an SPN for the Microsoft Dynamics NAV Server service. The syntax is:
setspn -A InstanceName/FullyQualifiedDomainNameOfServer:Port Domain\User
Using NAVSERV, which is the computer running Microsoft Dynamics NAV Server, and DynamicsNAV, which is the default instance name for Microsoft Dynamics NAV Server, the actual command has the following format:
setspn -A DynamicsNAV/NAVSERV.yourDomain.yourCompany.com:7046 yourDomain\yourUser
Replace "yourDomain," "yourCompany," and "yourUser" with the appropriate values.
3. Create an SPN for the SQL Server service. This service runs on the NAVSQL computer with a default instance name of MSSQLSvc. Type the following command:
setspn -A MSSQLSvc/NAVSQL.yourDomain.yourCompany.com:1433 yourDomain\yourUser
Again, replace "yourDomain," "yourCompany," and "yourUser" with the appropriate values.
