Multiple UNC Provider (MUP)

What is MUP (Multiple UNC Provider)?

A component of the Microsoft Windows NT operating system that supports the Workstation service by enabling access to shared folders and printer-sharing using Universal Naming Convention (UNC) paths.

How It Works

When an application tries to access a shared resource using a UNC path, the request first goes to the I/O Manager, which forwards it to the Multiple UNC Provider (MUP). The MUP then queries the installed redirectors to determine which one can access the shared resource. It then passes the request to the redirector.
