Configure IIS for an HTTP Receive Location

The HTTP receive location uses an application within Internet Information Services (IIS). This topic lists the steps to enable the HTTP receive location within IIS.

Depending on your operating system, the steps to configure the IIS application may vary. Use these steps as a guide, as the user interface may be different on your OS.

32-bit vs 64-bit

An HTTP receive location uses the BTSHTTPReceive.dll. There is a 32-bit and a 64-bit version of the DLL. You choose which version you want to use. 64-bit processes have more available memory, so if you process larger messages, then the 64-bit version may be best.

  • 32-bit install location: ..\Program Files (x86)\Microsoft BizTalk Server <version>\HttpReceive
  • 64-bit install location: ..\Program Files (x86)\Microsoft BizTalk Server <version>\HttpReceive64

To run the 64-bit version of the HTTP receive adapter in 64-bit native mode, open a command prompt, and execute the following scripts:

  1. Type: cscript %SystemDrive%\inetpub\AdminScripts\adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 0

  2. Type: C:\WINDOWS\Microsoft.NET\Framework64\vX.X.XXXXX>aspnet_regiis.exe -i


Any IIS configuration that leads to SOAP and HTTP sharing the same process is not valid. You can have only one isolated receiver per process.

Configure the IIS application

  1. Open Internet Information Services (open Server Manager, select Tools, and select Internet Information Services Manager).

  2. In IIS, select your server name. In the Features View, double-click Handler Mappings. In the Actions pane, select Add Script Map.


    When you configure the script mapping at the web server-level, the mapping applies to all web sites. If you want to restrict the mapping to a specific Web site or virtual folder, select that web site or folder, and then add the script map.

  3. In Add Script Map, select Request path, and type BtsHttpReceive.dll.

  4. In Executable, select the ellipsis (), and browse to \Program Files (x86)\Microsoft BizTalk Server <VERSION>\HttpReceive. Select BtsHttpReceive.dll, and then select Open.

  5. In Name, enter BizTalk HTTP Receive, and then select Request Restrictions. In this window:

    1. In Verbs, select One of the following verbs, and enter POST.

    2. In Access, select Script, and then select OK.

    3. When prompted to allow the ISAPI extension, select Yes.

  6. Create a new application pool (right-click Application Pools, select Add application pool). Name your application pool (such as BTSHTTPReceive), select NET Framework v4.0.30319, and select OK.


    The .NET version number may vary depending on the version of .NET Framework installed on the computer.

    The new application pool is listed.

  7. Select your new application pool, and open the Advanced Settings (Actions pane). In this window:

    • Enable 32-Bit Application: Set to True if you chose the 32-bit BtsHttpReceive.dll
    • Process Model section, Identity: Select the ellipsis (), select Custom account, and then Set it to an account that is a member of the BizTalk Isolated Host Users and IIS_WPG groups. Select OK.
  8. Add a new application to the web site (right-click the Default Web Site, select Add Application). In this window:

    1. Alias : Enter an alias that you associate with the application (such as BTS HTTP Receive, and then Select.

    2. Select the new application pool you just created, and then select OK.

    3. Physical path: Select the ellipsis (), and browse to \Program Files (x86)\Microsoft BizTalk Server <VERSION>\HttpReceive.

    4. Test Settings to verify there are no errors in the Test Connection dialog box. Close, and then select OK.


      If Test Settings returns a warning, the identity of the application pool may be missing permissions to a folder, or access to a group. As a troubleshooting step, select Connect As, enter the User name and Password for a user account that is a member of the Administrators group.

  9. The new application appears is listed under Default Web Sites.
