Microsoft Resource Kits - Windows 2000 Resource Kit

Pathman.exe  (Windows 2000 Resource Kit)

The Windows 2000 Resource Kits help IT professionals deploy, manage, and support Windows 2000 operating systems.
There are a number of Windows 2000 Resource Kit software tools available for free download from Microsoft. These tools are listed below, and can help you streamline administrative tasks such as managing Active Directory™, administering security features, working with Group Policy and Terminal Services, automating application deployment, and other important jobs.

Pathman.exe
This command-line tool enables you to add or remove components of both the system and user paths. It can modify any number of paths in a single call and includes error checking that can handle path abnormalities such as repeated entries, adjacent semicolons, and missing entries. Windows 2000 manages two different types of paths; the current user's path and the system path. Windows 2000 keeps a separate user path for every user on a system, but there is only one global system path. When a user logs on to a computer running Windows 2000, these two paths are combined to create the user's full path. For backward compatibility, Windows 2000 also loads path information from old Autoexec.bat files left in the root directory.
