Oleview.exe - Windows 2003 Resource Kit Utility

This administration and testing tool enables you to browse in a structured way, configure, activate, and test all of the Microsoft Component Object Model (COM) classes installed on your computer. Using this tool, you can also configure local or system-wide COM settings, including security settings, and enable or disable Distributed COM. You can activate COM classes locally or remotely, which is helpful for testing Distributed COM setups. OleView fully supports the Component Categories specification, which is a core COM technology.
