Some Microsoft Dynamics NAV 2009 components are Windows services: processes that remain in memory, function without user intervention, and serve other processes as needed.
Windows services must log on to an account to access resources and objects on the operating system. If all your Microsoft Dynamics NAV components run on a single computer you do not need to configure Windows services. If you have installed different components on different computers, then you may need to configure one or more services to be able to communicate with other Microsoft Dynamics NAV 2009 components.
The following components run as Windows services:
-
The NAV Server logs on using the NT Authority\Network Service account by default. If the NAV Server and SQL Server are on different computers, Microsoft recommends that you configure the NAV Server to log on using a dedicated Windows domain user account. This account should not be an administrator either in the domain or on any local computer.
-
The Application Server also uses the NT Authority\Network Service account by default. If Application Server and the database server (either SQL Server or the Classic Database Server) are on different computers, Microsoft recommends that you configure the Application Server to log on using a dedicated Windows domain user account that is recognized by the database server service. This account should not be an administrator either in the domain or on any local computer.
-
SQL Server (MSSQLSERVER)
Microsoft Dynamics NAV 2009 Setup does not install the SQL Server service, though it will install the SQL Server Express service (SQLEXPRESS) if you use Setup to install the Demo Install Option or to install the Database Components Option on a computer where SQL Server is not already installed.
The SQL Server service uses the Local System account by default. We recommend that you use a local user or domain user account instead.
NoteTo configure the MSSQLSERVER service, you should use SQL Server Configuration Manager instead of the Control Panel Services tool, as described below. Using SQL Server Configuration Manager assures that additional permissions required for the SQL Server service account are granted. The procedure is essentially the same: select the MSSQLSERVER service and navigate to the Log On tab.
Configuring a Service
The following procedure assumes a Server operating system (Windows Server 2003 or 2008). For Windows XP or Windows Vista, the steps are slightly different but the process is essentially the same.
Configuring a service
-
In Control Panel, click Administrative Tools, and then click Services.
-
In the list of services, double-click the service that you want to configure.
-
In the Server Properties dialog box, go to the Log On tab.
-
Select This account and either enter or browse to the account that you want the service to use.
-
Enter and confirm the password for this account.
-
Click OK to exit the Server Properties dialog box.
