Dynamics 365 Dynamics NAV 2017

Multiple webclients on one Server

While installing NAV, It automatically sets up a Webclient Instance as well But it doesn’t do the same when we create a new separate Instance. To have multiple webclients we need to set them up manually.

  1. Identify the instance for which we need webclient.
  2. Open Powershell ISE as Adminstrator and run the following command
New-NAVWebServerInstance -WebServerInstance <name of webservice instance> -Server localhost -ServerInstance <NAV server Instance name>


Replace <name of webservice instance> with the name you want. This is the name that you will need to type in browser to access the webclient

Replace <NAV server Instance name> with the name of your nav server instance


  1. This creates a new webservice instance which can be checked at C:\inetpub\wwwroot


  1. Lets try to access the webclient now. We can use the url http://localhost:8080/<name of webservice instance> /webclient. Unfortunately you will be greeted by the following generic error screen.




  1. To fix this we need to make a couple of changes to the config file which can be found at

C:\inetpub\wwwroot\<name of webservice instance>\web.config.

We need to change the value of  <add key=”ClientServicesPort” value=”XXXX” /> to the correct client service port of your instance.

After this change the webclient should start working fine.
