Microsoft Internet Information Services (IIS) provides a Web application infrastructure for many BizTalk Server features. BizTalk Server requires IIS for the following features:
- HTTP adapter
- SOAP adapter
- Windows SharePoint Services adapter
- Secure Sockets Layer (SSL) encryption
- BAM Portal
📝 One-Minute Brief
Microsoft Internet Information Services (IIS) is a foundational requirement for BizTalk Server features like the HTTP/SOAP adapters and the BAM Portal. This guide details the step-by-step installation of IIS 8 on Windows Server 2012, highlighting the specific Role Services and Features (like ASP.NET 4.5 and IIS 6 Management Compatibility) required for a successful setup. Crucially, it also explains how to enable 32-bit mode for the BAM Portal in a 64-bit environment.
To install IIS 8, use the following steps:
- Open Server Manager.
- Under the Manage menu, select Add Roles and Features (or press Add roles and features under the Dashboard panel)

- On the Before You Begin screen, click Next.

- On the Installation Type screen, select Role-based or feature-based installation and click Next.

- On the Server Selection screen, select the appropriate server, leave the default options, and click Next.
- Select a server from the server pool.
- local is selected by default.

- On the Server Roles screen, select the Web Server (IIS) option.

- Then click Next.
- On the Web Server Role (IIS) screen, click Next.
- On the Role Services screen under Web Server Role (IIS), we will customize our installation of IIS with the following options:
- Common HTTP Features
- Default Document
- Directory Browsing
- HTTP Errors

- Click Close to exit the wizard
Running the BAM Portal in a 64-bit Environment
BAM Portal runs only in a 32-bit mode. If you are using Internet Information Services (IIS) in a 64-bit environment, you must set IIS to 32-bit mode to run the BAM portal. To do this, follow these steps:
- Open a command prompt and run the adsutil command. To do this, press the Windows key to switch to Metro UI, type cmd, and click on the Command Prompt option on the Apps menu.
- Type the following at the command prompt:
- cscript c:\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
- Close the command prompt.
Or:
- Press the Windows key to switch to Metro UI.
- Type Internet Information Services (IIS) Manager or IIS and click on the Internet Information Services (IIS) Manager option on the Apps menu.
- Expand the server and click on Application Pools to display available application pools in the center panel.
- Right-click on DefaultAppPool and select Advanced Settings.

- Change the value of Enable 32-bit Applications from False to True. Click OK.

I like to set the BAM AppPool as 32-bit and leave the default at 64-bit.
