Microsoft Dynamics NAV 2009 introduces a new three-tier RoleTailored architecture that improves the security, scalability, and flexibility of Microsoft Dynamics NAV. For details, see RoleTailored Architecture. In this walkthrough, you will install the new architecture in a production environment on three computers:

Computer Installed operating system and software Tier


Server computer running Windows Server 2008 or Windows Server 2003, and Microsoft SQL Server 2008 or SQL Server 2005

Database tier


Server computer running Windows Server 2008 or Windows Server 2003 and Microsoft Dynamics NAV Server

Server (middle) tier


Client computer running Windows Vista

Client tier

The key characteristic of this walkthrough is that the client, Microsoft Dynamics NAV Server, and SQL Server are installed on separate computers. In a production environment, you may have multiple computers running SQL Server, multiple computers running Microsoft Dynamics NAV Server, and multiple computers running the RoleTailored client. But as long as you do not install multiple Microsoft Dynamics NAV tiers on the same computer, the procedures and issues presented in this walkthrough are relevant.

For information about the steps involved in installing both Microsoft Dynamics NAV Server and SQL Server on a single computer, see Walkthrough: Installing the Three Tiers On Two Computers.


The content in this walkthrough only applies to Microsoft Dynamics NAV 2009 SP1. For Microsoft Dynamics NAV 2009 content, see Developer and IT Pro Help for Microsoft Dynamics NAV 2009.
