There are two tools you can use to operate Microsoft SMTP Service. The first, Internet Service Manager, can be administered within a local area network (LAN). The second, Internet Service Manager (HTML), can be accessed using a Web browser.
Configuration options are the same in both tools, with exceptions in some logging and security features. This documentation is written based on the use of Internet Service Manager. If a procedure or option differs for Internet Service Manager (HTML), it is noted in the text.
You can operate Microsoft SMTP Service from Microsoft Management Console (MMC) in Internet Service Manager. The service is a snap-in component to MMC. All other installed IIS services are also available under MMC.
With Internet Service Manager (HTML), you can operate Microsoft SMTP Service remotely using Hypertext Transfer Protocol (HTTP). To use this tool, you must use Microsoft® Internet Explorer version 3.0 or later, or another Web browser. The configuration options are the same in Internet Service Manager (HTML) as in Internet Service Manager, with several exceptions. You cannot grant operator permissions to individual Windows NT Server accounts using Internet Service Manager (HTML), or grant and deny access to specific computers. The transaction logging feature is also unavailable.
Navigation is also slightly different in Internet Service Manager (HTML). While the options are basically the same, you access them directly from the screen instead of from a menu.
