HOW TO set NAV Service Startup Type via PowerShell

When you create a new Instance using the command New-NAVServerInstance it will set the Startup Type of the NAV Service as “Automatic” by default.

I haven’t found any NAV command to change it, so let us think about NAV Service as any other Windows Service.

In PowerShell there is a command Set-Service that allows to change an existing Service.

NAV Service names have the following format

MicrosoftDynamicsNavServer$<ServerInstance>

where <ServerInstance> is the name of the NAV Instance

So running the following command we can change the Startup Type to Automatic, Manual or Disabled.

Set-Service –Name "MicrosoftDynamicsNavServer`$DynamicsNAV100" –StartupType Manual

This example will set the NAV Service for the Server Instance DynamicsNAV100 to Manual.

Unfortunately -StartupType parameter does not have a value for Automatic (Delayed Start)

So it seams a bit tricky but just looking into the register I’ve noted that the other services that had Automatic (Delayed Start) as Startup Type have a REG_DWORD value called “DelayedAutoStart” with value 1 under HKLM\System\CurrentControlSet\Services\

So the idea is use the previous command to set the Startup Type to Automatic then add REG_DWORD via script

Set-Service –Name "MicrosoftDynamicsNavServer`$DynamicsNAV100" –StartupType Automatic
Set-ItemProperty -Path "Registry::HKLM\System\CurrentControlSet\Services\MicrosoftDynamicsNavServer`$DynamicsNAV100" -Name "DelayedAutostart" -Value 1 -Type DWORD

In reality we could setup everything from the registry

Set-ItemProperty -Path "Registry::HKLM\System\CurrentControlSet\Services\MicrosoftDynamicsNavServer`$DynamicsNAV100" -Name "Start" -Value 2 -Type DWORD
Set-ItemProperty -Path "Registry::HKLM\System\CurrentControlSet\Services\MicrosoftDynamicsNavServer`$DynamicsNAV100" -Name "DelayedAutostart" -Value 1 -Type DWORD

NOTE 1: Both scripts will work only if the current Startup Type is different of Automatic
NOTE 2: “DelayedAutostart” DWORD will have effect only if you setup the Service Type as Automatic.

HOW TO create NAV Instances with multiple builds in the same machine

The concepts described in this post are applicable to different versions/builds, for the examples I will use an installation of NAV 2013 R2 (7.1.35473) and I will create one or more instances also for the build 7.1.36703 (Cumulative Update 7 – May 2014) in the same server.

HOW TO create NAV Instances with multiple builds in the same machine?

We have to distinguish two different operations:

  1. Creation of the first instance for a different build
  2. Add more instances for this build

HOW TO create the first instance for a different build?

Prerequisites:

After you installed NAV 2013 R2 Server side’s files will be inside the following path:

C:\Program Files\Microsoft Dynamics NAV\71\

Copy the folder 71 in a new folder 71 – Build 36703

C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\

Copy and replace all files from the NST folder, in the Cumulative Update package, to the Service folder in the following path:

C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\

Run Microsoft Dynamics NAV 2013 R2 Administration Shell and execute the following PowerShell CmdLet:

New-Service 'MicrosoftDynamicsNAVServer$NewInstanceName' -BinaryPathName '"C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\Microsoft.Dynamics.Nav.Server.exe" $NewInstanceName /config "C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\Microsoft.Dynamics.NAV.Server.exe.config"' -DependsOn 'HTTP' -Description 'Service handling requests to Microsoft Dynamics NAV application.' -DisplayName 'Microsoft Dynamics NAV Server [NewInstanceName]' -StartupType Manual

Note: you can replace NewInstanceName with your preferred name (there are 3 references) or use another name for the folder “71 – Build 36703” (there are 2 references)

In case of error, to delete this service use the following PowerShell CmdLet:

sc.exe delete 'MicrosoftDynamicsNAVServer$NewInstanceName'

Note: don’t remove the instance using Microsoft Dynamics NAV 2013 R2 Administration because, this is the Default instance for this build and it will be removed the Service folder from the 71 – Build 36703 folder.

HOW TO add more instances for this build?

In my example the name will be SecondInstanceName

Method 1:
Using Microsoft Dynamics NAV 2013 R2 Administration tool create a new instance with name SecondInstanceName.

Copy the SecondInstanceName folder from

C:\Program Files\Microsoft Dynamics NAV\71\Service\Instances\

to

C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\Instances\

Note: if the subforder Instances doesn’t exist create it.

Using Microsoft Dynamics NAV 2013 R2 Administration tool delete the instance with name SecondInstanceName.

Run Microsoft Dynamics NAV 2013 R2 Administration Shell and execute the following PowerShell CmdLet:

New-Service 'MicrosoftDynamicsNAVServer$SecondInstanceName' -BinaryPathName '"C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\Microsoft.Dynamics.Nav.Server.exe" $SecondInstanceName /config "C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\Instances\SecondInstanceName\SecondInstanceName.config"' -DependsOn 'HTTP' -Description 'Service handling requests to Microsoft Dynamics NAV application.' -DisplayName 'Microsoft Dynamics NAV Server [SecondInstanceName]' -StartupType Manual

The difference with the previous command is only that now we will refer to the config file inside the Instances folder.

Note: you can replace SecondInstanceName with your preferred name (there are 5 references) or use another name for the folder “71 – Build 36703” (there are 2 references)

The last step is to correct the config files inside the SecondInstanceName folder:

  • SecondInstanceName.config – correct the paths in appsettings and tenants node replacing “71” with “71 – Build 36703”
  • CustomSettings.config – insert the correct values and ports and don’t foget to refer to the Default instance for this build in the following key:
    <add key="ServerInstance" value="NewInstanceName" />

Method 2 (by ROEL BERGS):

  1. Change a registry key to the path of the new build
  2. create the SecondInstanceName using Microsoft Dynamics NAV 2013 R2 Administration tool or PowerShell (CmdLet New-NAVServerInstance). This method will create the Instance foder in the correct path.
  3. Changed the registry key value back to the default path.

Following and example of the PowerShell script (run Microsoft Dynamics NAV 2013 R2 Administration tool as Administrator):

$nstDefaultPath = "C:\Program Files\Microsoft Dynamics NAV\71\Service\"
$nstPath = "C:\Program Files\Microsoft Dynamics NAV\71 - Build 36703\Service\"

#Switch registry to correct path
set-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft Dynamics NAV\71\Service" -name "Path" -value $nstPath

New-NAVServerInstance "SecondInstanceName" -DatabaseName "DBNAME" -DatabaseServer "SQLSERVER" -ClientServicesPort 7046 -SOAPServicesPort 7047 -ODataServicesPort 7048 -ManagementServicesPort 7045

#Switch registry to default
set-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft Dynamics NAV\71\Service" -name "Path" -value $nstDefaultPath

Note: don’t foget to insert set the corret values in the parameters and you can replace SecondInstanceName with your preferred name (there is 1 reference) or also use another name for the folder “71 – Build 36703” (there is 1 reference).

The last step is to correct the config file inside the SecondInstanceName folder:
CustomSettings.config – insert the correct values and ports and don’t foget to refer to the Default instance for this build in the following key:

<add key="ServerInstance" value="NewInstanceName" />
