SharePoint Explorer. The Dot Net Factory’s SharePoint Explorer is an Internet Explorer add-on that provides users with an easy to use way to navigate any SharePoint Portal or Windows SharePoint Services site. SharePoint sites suffer from a lack of a unified hierarchical view of what sites you have access to, how to get there, and where you are in the hierarchy. SharePoint Explorer is the first client-based product to address this navigation issue for browsing any SharePoint site. SharePoint Explorer displays an explorer-like navigation tree of the Areas, Sites and Sub-Sites for the servers you select. SharePoint Explorer also provides powerful features for administrators, including links to common administrative tasks. For an administrative user, these task links are presented in the Admin Tasks node.

The Dot Net Factory’s Active Directory WebManager is a completely web-based user and group administration tool. Its flexible architecture allows it to be deployed both as a powerful tool for expert administrators as well as a task-restricted interface for delegated management by less technical or even casual business users.
