System requirements for IIS applications vary for the development computer, the deployment computer, and the end-user's computer.
To create and test IIS applications, you need to have Internet Explorer 4.0 and a Web server installed on your development computer that is capable of running Active Server Pages. You can use any of the combinations in the table below for development purposes:
| Operating System | Web Server |
| Windows NT Server 4.0 or later | Internet Information Server 3.0 or later, with Active Server Pages |
| Windows NT Workstation 4.0 or later | Peer Web Services 3.0 or later, with Active Server Pages |
| Windows 95 or later | Personal Web Server 3.0 or later, with Active Server Pages |
Important If you are using Windows NT Server or Windows NT Workstation, you must have Service Pack 3.0 installed.
Important The version of Personal Web Server installed with Microsoft FrontPage 98 does not run Active Server Pages and will not work with IIS applications. If you are using Personal Web Server, you must install Personal Web Server for Windows 95 or Windows NT Service Pack 3.0 or later.
For deployment purposes, you should have Internet Information Server (with Active Server Pages) installed on your Web server, along with any supplemental system such as database applications that are needed by your application.
End users of an IIS application must have a browser installed. Although Internet Explorer 4.0 or later is recommended, any browser can act as the front end of an IIS application.
Note If your webclass is set to stay alive between requests, the end user must have a browser that supports cookies and cookies must be enabled. For more information, see "Moving State Between the Browser and the Web Server."
