The nacmnlib3_71.dll file is a naCmnLib module that works with McAfee Agent from McAfee, Inc.  This file belongs to McAfee’s antivirus software and is part of the network scanning functions.  An error with this file may disable some of the live scanning functions of McAfee.  You might be able to solve the issue by reinstalling McAfee, but the problem is most likely in your computer registry.

The registry is a database that Windows uses to track all the files installed on your computer.  When Windows runs a piece of software, it checks in the registry to find what files it needs.  A mistake in a registry entry can mean that Windows won’t be able to locate necessary files, and your software won’t work.
