The Network Compatibility Test (NCT) verifies the compatibility between networking environments and Microsoft Windows version 3.1. The NCT shell is a Windows application which starts the tests, keeps track of test results, and provides an onscreen report. You can also use several tests as standalone test tools during the development and debugging stages of your driver. For a complete description of the tests and an explanation of how to use them, see the NCT.DOC file that you installed with the NCT.
