These are the minimum Microsoft IIS configuration settings for a web thin client project.
Depending on your network and operating system environment, additional settings, such as user security, may need to be configured.
To configure Microsoft IIS for web thin client projects:
-
If Microsoft Internet Information Services (IIS) isn't enabled on your computer, turn on IIS for thin client access.
-
Open the Internet Information Services (IIS) Manager. The IIS icons and the Start button circled in red (below) will be used for this procedure.

-
In the Connections pane, select (click) Default Web Site. Then, in the Actions pane, click Basic Settings.... In the Edit Site dialog, use the Physical path browse button to select the Web folder of your project as shown below, and click OK to close the dialog.

-
Right-click Default Web Site to open the Site Bindings dialog. If necessary use the Add and Edit buttons to set the Port to 80 as shown below.

-
If your web server is behind a Proxy, check the Enable HTTP keep-alive checkbox. This setting can be enabled always (and is the default setting).
To get to this setting, double-click the HTTP Response Headers icon in the center pane of the Internet Information Services (IIS) Manager (circled in red above). This changes the center pane to HTTP Response Headers and changes the options in the Actions pane. In the Actions pane, click Set Common Headers to open the Set Common HTTP Response Headers dialog. Check the Enable HTTP keep-alive checkbox if it is not already checked. Then click OK to close the dialog. The arrow in the upper left corner of the dialog (circled below) can be used to navigate back to the main view in the center pane of the Internet Information Services (IIS) Manager.

-
Add the screen file to the list of MIME types. To do this, double-click the MIME Types icon in the center pane of the Internet Information Services (IIS) Manager (circled in red above). This changes the center pane to MIME Types and changes the options in the Actions pane. In the Actions pane, click Add to open the Add MIME Type dialog. Fill in the Fine name extension field with .scc and the MIME type field with application/studio as shown below. Click OK to close the dialog, and use the arrow in the upper left corner of the dialog (circled below) to navigate back to the main view in the center pane of the Internet Information Services (IIS) Manager.

-
Depending on your network security, you may need to settings for Anonymous Authentication (double-click the Authentication icon) or secure communication (double-click the Server Certificates icon). Check with your network administrator and check Microsoft documentation for more information.
-
If necessary, start IIS by using the Start button in main Actions pane (
), circled in the first IIS Manager image above.
