Installation > Installation Pointers

Prerequisites

•	Microsoft SQL Server 2005, Microsoft SQL Server 2005 Express Edition with Service Pack 2, Microsoft SQL Server 2008, or Microsoft SQL Server 2008 Express Edition (Note also, some crashes are known to occur with SQL Server 2005 under heavy load when SP2 is not installed.).

•	Although it is not required, if you are using SQL Server Express, we also recommend you download the SQL Server Express Management Console.

•	Microsoft Internet Information Server (Note: If IIS 7.0 is being used, IIS 6.0 Compatibility Scripts must be installed from the Windows Add/Remove Windows Components dialog.)

•	Microsoft ASP.NET Ajax Extensions 1.0

•	Prepare the filesystem(s) being used for storage of DICOM studies. The filesystem must be accessible.

ASP.NET Registration

There is a known issue if you install/enable IIS after installing the .NET 2.0 framework, you must register ASP.NET with IIS in order for IIS to know how to process ASP.NET files. The following command can be run from a command prompt (note that the command would have to be adjusted if your Windows directory is different):

32-Bit: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

64-Bit: C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i

SQL Server and SQL Server Express

If you're using SQL Server 2005/2008 Express Edition, TCP/IP connections to SQL Server must be enabled and the SQL Server Browser must be enabled. This is done through the SQL Server configuration manager. This application can be accessed from All Programs >> Microsoft SQL Server 2005/2008 >> Configuration Tools >> SQL Server Configuration Manager. Under the SQL Server Network Configuration folder, TCP/IP must be enabled. Under the SQL Server 2005/2008 Services folder, SQL Server Browser must be enabled.

For more help on SQL Server 2005 Express configuration, see SQL Server 2005 Express Guide.

The ImageServer installer requires SQL Server 2005 to be configured with SQL Authentication to be enabled. After installation, the software can be used with Windows Authentication.

Windows Server 2003 .NET 2.0 Support

By default, Windows Server 2003 comes with .NET 1.1 installed with ASP.NET. The ImageServer requires ASP.NET 2.0. After ensuring that .NET 2.0 is installed, and is registered with IIS, the following procedure is required:

•	Open Internet Information Systems (IIS) Manager

•	Right-click on the default web site and click 'Properties'.

•	Click on the ASP.NET tab.

•	Select ASP.NET 2.0 as the default version.

Windows Server 2008 R2 Support

On a clean install of Windows Server 2008 R2, by default IIS does not allow serving of static content. In this configuration, all of the images and graphics within the ImageServer Web GUI cannot be displayed. The serving of static content must be enabled within IIS for the ImageServer Web GUI to work properly.
