Configuring Microsoft Dynamics NAV Server

Applies to: Microsoft Dynamics NAV 2017. See Microsoft Dynamics NAV 2018 version.

When you run Microsoft Dynamics NAV 2018 Setup and install Microsoft Dynamics NAV Server, you can provide configuration information that is then used as the configuration for the default Microsoft Dynamics NAV Server instance.

After you install Microsoft Dynamics NAV Server, you can change any of the settings that you provided during Setup, or any of the Microsoft Dynamics NAV Server settings, using either the Microsoft Dynamics NAV Server Administration tool or the Dynamics NAV Windows PowerShell cmdlets for Microsoft Dynamics NAV 2018.

Note

Each Microsoft Dynamics NAV Server instance has its own settings.

Configuring Microsoft Dynamics NAV Server in Setup

You can configure the default instance of Microsoft Dynamics NAV Server when running Microsoft Dynamics NAV 2018 Setup. You must first select Microsoft Dynamics NAV Server as a component to install. To do this, select one of the following Installation Options that includes Microsoft Dynamics NAV Server:

  • Server Option

  • Developer Option

    You can also customize your installation and the list of components to install. For more information, see How to: Choose Components to Install.

    After you specify an installation option or customize your component list, the Specify parameters pane is displayed in Setup. The list of parameters that you see in the Specify parameters pane depends on which components you have selected for configuration. Setup provides a short description for each parameter. For a description of the most important parameters for Microsoft Dynamics NAV Server, see Server Option.

    When you have finished entering values, choose the Apply button. This returns you to the Specify parameters page in Setup.

    After you finish running Setup, you can modify Microsoft Dynamics NAV Server using any of the methods described in the following section.

Configuring Microsoft Dynamics NAV Server After Installation

After you install Microsoft Dynamics NAV Server, you can change any of the settings that you provided during Setup, or any of the Microsoft Dynamics NAV Server settings, in any of the following ways:

Important

After you modify a Microsoft Dynamics NAV Server setting, you must restart the associated Microsoft Dynamics NAV Server instance before any changes can take effect.

In the tables in the following sections, Microsoft Dynamics NAV Server Administration tool setting names are used. Settings names in the CustomSettings.config file are slightly different. Quotation marks are required for all values.

Note

You must choose Edit in the Microsoft Dynamics NAV Server Administration tool before you can modify any values.

General Tab Settings

The following table describes fields on the General tab in the Microsoft Dynamics NAV Server Administration tool.

Setting Description
Build Restriction Specifies what happens when a Dynamics NAV client tries to connect to the Microsoft Dynamics NAV Server instance when the client is running a different build version of Microsoft Dynamics NAV 2018 than the server instance.

Values:

AlwaysConnect

WarnClient
Before connecting the client to the server instance, a message appears that informs the user that the build versions for the client and server instance are different. The user can choose to continue or cancel the connection.

DoNotAllow
A message appears that informs the user that the client and server instance build versions are different, and the client does not connect to the server instance.

Default: WarnClient

Note: With the Microsoft Dynamics NAV Web client and Microsoft Dynamics NAV Tablet client, this setting compares the build version of the Microsoft Dynamics NAV Web Server components on IIS with the Microsoft Dynamics NAV Server instance. It controls the connection between Microsoft Dynamics NAV Web Server components and the server instance.
Certificate Thumbprint If you use security certificates to protect communications between Microsoft Dynamics NAV Server and client services or web services over an open or wide-area network, you must provide the certificate thumbprint to Microsoft Dynamics NAV Server by updating this setting. For more information, see Walkthrough: Implementing Security Certificates in a Test Environment and How to: Implement Security Certificates in a Production Environment.
Compile and Load Business Application Specifies whether the Microsoft Dynamics NAV Server instance compiles all the business application assemblies and loads them to cache memory when the server instance is started. The assemblies are then retrieved from memory when requested by a Dynamics NAV client.

Enabling this setting will reduce the time it takes for the server instance to load application objects the first time they are requested by a Dynamics NAV client after the server instance started. However, it will also slightly increase the memory usage by the server instance.

If you enable this setting, when the server instance starts for the first time, the business application assemblies will be compiled and loaded to the cache memory of the computer that is running the server instance. The assemblies, along with metadata such object timestamp information, are also stored to a temporary folder on the computer's file system. Whenever the server instance is restarted, it will compare the assemblies that are stored in memory with corresponding objects in the connected database to determine whether the assemblies in memory can be reused. An assembly will be reused if the following conditions are met:

- The connected database is the same as before, based on the databasemagic field in the dbproperty table.

- The object time stamp that is recorded on the compiled assembly matches the object timestamp in metadata of the connected database.

If the conditions are not met for an assembly or an assembly for an object in the database is not found in the memory, then a new assembly is built and stored for reuse to cache memory and the file system of the server instance compute for reuse.

If you disable this setting, individual assemblies will be compiled on-demand as application objects are requested by the Dynamics NAV client. The compiled assemblies will not be reused on subsequent server instance restarts.

Notes:
  • This setting does not apply to query objects.
  • Assembly compilation happens asynchronously.
  • On average, all application objects will be loaded within the first few minutes that the server instance operates.
Credential Type Specifies the authentication mechanism for Dynamics NAV users of this Microsoft Dynamics NAV Server instance.

The options are Windows, Username, NavUserPassword, AccessControlService, and None. For more information, see Users and Credential Types.

If you choose AccessControlService, you must specify a token signing key for use with Azure Access Control service (ACS), or a federation metadata location for use with Azure AD. If you choose NavUserPassword, and you specify a token signing key, you can use both NavUserPassword and AccessControlService for this server instance.

Notes:
  • None is for internal use on system sessions and typically should not be used. If you choose None, then the Microsoft Dynamics NAV Server instance cannot start.
  • ExchangeIdentity and TaskScheduler are for internal use only, and should not be used.

The setting has the following values, which correspond to the event severity levels (listed from highest to lowest level): Critical, Error, Warning, Normal (this corresponds to the Information level), and Verbose.

You use this setting to filter out lower-level events from the log. For example, if you set this setting to Error, only Error and Critical events will be logged.

Note: Events are recorded in the Microsoft Dynamics NAV Server channel logs, which you can see in Event Viewer, under Applications and Services Logs.
Enable Certificate Validation Specifies whether validation should be performed on the security certificate.

Default: Enabled
Enable Debugging Specifies whether the Microsoft Dynamics NAV Server instance starts with debugging enabled.

If this option is enabled, the following occurs:

When the client first connects, all C# files for the application are generated. C# files persist between Microsoft Dynamics NAV Server restarts. Application objects are compiled with debug information.

Default: Not enabled
Enable Event Logging to Windows Application Log Specifies whether to record admin and operational type events (errors, warnings, and information messages) that occur on Microsoft Dynamics NAV Server instances in the Windows Application log on the computer that is running Microsoft Dynamics NAV Server.

Because Microsoft Dynamics NAV Server instance events are always logged to the Application and Services Logs, you can disable logging Microsoft Dynamics NAV Server instance events in the Windows Application log and not lose any data. For more information, see Monitoring Dynamics NAV Server Events Using Event Viewer and How to: Disable Logging Events to the Windows Application Log.

Important: If you are using System Center Operations Manager to monitor Microsoft Dynamics NAV Server instances, do not disable logging to the Windows Application log. If you do, monitoring will not work.
Enable File Access by C/AL Functions Specifies whether C/AL functions of the file data type can access files on the Microsoft Dynamics NAV Server computer.

Default: Enabled
Enable Full C/AL Function Tracing Specifies whether full C/AL function tracing is enabled on Event Tracing for Windows (ETW) sessions.

The App ID URI is typically the same as the value of wtrealm parameter of the ACSUri setting that is included in web.config file for the Microsoft Dynamics NAV Web client and the ClientUserSettings.config file for the Microsoft Dynamics NAV Windows client.

An example of an App ID URI is https://localhost:7047/.

For more information about how to use the Azure Active Directory App ID URI with OAuth authentication, see Using OAuth to Authenticate Microsoft Dynamics NAV Web Services (Odata and SOAP).
Enable Membership Entitlement Configures the server instance to use membership entitlement for controlling access the Dynamics NAV.

This setting is typically only used for software as a service (SaaS) solutions.
Excel add-in AAD client app ID This setting is used to set up the Excel Add-in that enables users to use Excel to modify and update Dynamics NAV data.

The setting specifies the client ID of the Azure AD tenant that is used for the Excel add-in. The Excel add-in requires a separate Azure AD tenant. For more information, see Configuring Dynamics NAV and the Excel Add-In.
Extended Security Token Lifetime Specifies the number of hours that are added to the lifetime of Azure AD security tokens, which are used to authenticate client users. When the lifetime expires, the client is disconnected from the server instance. An event with a message such as "The SAML2 token is invalid because its validity period ended." is recorded in the event log for the server instance. In general, the lifetime of security tokens is 1 hour.

The valid range of this setting is from 0 to 24 hours. The default value is 0.
WS-Federation Login Endpoint Specifies the URL for the federation sign-on page that Dynamics NAV redirects to when configured for single sign-on.

You must specify a URL in the following format:

https://login.microsoftonline.com/[AADTENANTID]/wsfed?wa=wsignin1.0%26wtrealm=...%26wreply=....

The placeholder [AADTENANTID] represents the GUID of your Azure AD tenant. If the server instance has to support multiple Azure AD tenants, then the Azure AD Tenant ID parameter that is specified when mounting a tenant replaces the placeholder.
WS-Federation Metadata Location Specifies the URL for the federation metadata document that describes the configuration information for your Azure AD tenant. The federation metadata document is used to validate the security tokens that the Microsoft Dynamics NAV Web client and Microsoft Dynamics NAV Tablet client receive, and to establish a trust relationship with between Dynamics NAV and an application that you have added to Azure AD.

You must specify a URL in the following format:

https://login.microsoftonline.com/[AADTENANTID]/FederationMetadata/2007-06/FederationMetadata.xml

The placeholder [AADTENANTID] represents the GUID of your Azure AD tenant. If the server instance has to support multiple Azure AD tenants, then the Azure AD Tenant ID parameter that is specified when mounting a tenant replaces the placeholder.

This parameter is relevant only when Credential Type, on the General tab, is set to AccessControlService. For more information, see Authenticating Users with Azure Active Directory.

Task Scheduler Tab Settings

The following table describes fields on the Task Scheduler tab in the Microsoft Dynamics NAV Server Administration tool.

The task scheduler processes jobs and other processes on a scheduled basis. For more information about task scheduler, see Task Scheduler.

Setting Description
Enable Task Scheduler Specifies whether the server instance starts with the task scheduler enabled.

If this option is enabled, the server instance will process scheduled tasks.

Default: Enabled
Maximum Concurrent Running Tasks Specifies the maximum number of tasks that can run simultaneously on the server instance.

The value that you specify will depend on the hardware (CPUs) of the deployment environment and what you want to prioritize: client performance or scheduled tasks (such as job queue entries). The setting is particularly relevant when the server instance is used for both scheduled tasks and client services. If there are many jobs running at the same time, you might experience that the response time for clients gets slower. In which case, you could decrease the value. However, if the value is too low, it might take longer than desired for scheduled tasks to process. When you have a dedicated server instance for scheduled tasks, this setting is less important with respect to client performance.

Default: 10

Reports Tab Settings

The following table describes fields on the Reports tab in the Microsoft Dynamics NAV Server Administration tool.

Setting Description
Enable Save as Excel on Request Pages of RDLC-layout Reports Specifies whether users can open or save a report as an Microsoft Excel document if the report uses an RDLC layout.

If you clear this check box, the Excel option is removed from the Print menu on the request page.

Default: Enabled
Enable Save as Word on Request Pages of RDLC-layout Reports Specifies whether users can open or save a report as a Microsoft Word document if the report uses an RDLC layout.

If you clear this check box, the Word option is removed from the Print menu on the request page.

Default: Enabled
Enable Save from Report Preview Specifies whether users can save a report as a PDF, Microsoft Word, or Microsoft Excel document from the report preview window.

If you clear this check box, the Save As icon is removed from the report preview window.

Default: Enabled
Report PDF Font Embedding Specifies whether fonts are embedded in PDF files that are generated for reports when the report uses an RDLC report layout at runtime. This setting applies when reports are run and saved as PDF files on the client (from the report request page or print preview window) or on the server instance (by the SAVEAS function or SAVEASPDF function in C/AL code).

Note: This setting does not apply when a report uses a Word report layout at runtime.

Embedding fonts in a PDF of a report makes sure that the PDF will use the same fonts as the original file, regardless of where the PDF is opened and which fonts are installed on the computer. However, embedding fonts can significantly increase the size of the PDF files. By disabling font embedding, you can decrease the size of the report PDF files.

Note: This is a global setting for font embedding in report PDF files. You can override this setting on a report basis by the specifying the PDFFontEmbedding property.

Default: Enabled

Using Microsoft Dynamics NAV Administration Shell Cmdlets to Modify Settings

The Microsoft Dynamics NAV Administration Shell includes several cmdlets that enable you to create and modify Microsoft Dynamics NAV Server instances. Use the Set- cmdlets to modify a setting on a Microsoft Dynamics NAV Server instance. For example, you can change the value for DatabaseServer to DatabaseServer.Domain.Com for the server instance named MyInstance by executing this cmdlet:

Set-NAVServerConfiguration MyInstance -KeyName DatabaseServer -KeyValue DatabaseServer.Domain.Com  

To display all the Set- cmdlets on the Windows PowerShell console, use the following command:

Get-Help Set-NAVServer*  

For more information, see Microsoft Dynamics NAV Windows PowerShell Cmdlets
