Multiple Provider Router DLL
A system component that handles communications between the system and all network providers. The MPR calls the network provider functions that are exposed by each network provider.
the user-mode DLL that establishes network connections based on queries to WNet providers.
The Multiple Provider Router (MPR) handles communication between the Windows operating system and the installed network providers. It enables Windows to present an integrated network to the user. When the MPR starts, it checks the registry to determine which network providers are installed on the system and the order they should be cycled through. It loads all registered network provider DLLs and uses them to process subsequent WNet calls made by the user interface or other applications
