Configuring Web Server (IIS) Features

Before you install the Acumatica ERP server software, make sure that the following Web Server (IIS) features are turned on:

  • Web Management Tools > IIS Management Console
  • World Wide Web Services > Application Development Features > .NET Extensibility
  • World Wide Web Services > Application Development Features > ASP.NET

Setting Up an HTTPS Service in Web Server (IIS)

HTTPS is a secure communications channel that is used to exchange information between a client computer and a server. You may need to set up an HTTPS service in Web Server (IIS)—for example, if your users export data to Microsoft Excel and want to update the data automatically, or you want to use single sign-on (SSO).  To enable SSL in Web Server (IIS), you must first obtain a certificate that is used to encrypt and decrypt the information that is transferred over the network. You receive a certificate file from the certification authority, and then register the certificate with your Web Server (IIS). For instructions, refer to the documentation of your Web Server (IIS).

Enabling Semantic Search for Microsoft SQL Server

To access the full-text search functionality, you have to install the Semantic Search for the Microsoft SQL Server. For more information on searching in Acumatica ERP, see Managing Search in the
Acumatica ERP User Guide. To install Semantic Search, do the following:

  • Select Full-Text and Semantic Extractions for Search on the Features to Install page during Microsoft SQL Server setup.
