Dcdiag (Domain Controller Diagnostic Tool)

This command-line tool analyzes the state of domain controllers in a forest or enterprise and reports any problems to assist in troubleshooting. As an end-user reporting program, Dcdiag encapsulates detailed knowledge of how to identify abnormal behavior in the system. Dcdiag displays command output at the command line.

Dcdiag consists of a framework for executing tests and a series of tests to verify different functional areas of the system. This framework selects which domain controllers are tested according to scope directives from the user, such as enterprise, site, or single server.


NetDiag is a command-line, diagnostic tool that helps isolate networking and connectivity problems by performing a series of tests to determine the state of your network client and whether it is functional. These tests and the network status information they expose help network administrators and support personnel identify and isolate network problems. Moreover, because this tool does not require parameters or switches, you can focus on analyzing the output, rather than training users on tool usage.

NetDiag diagnoses network problems by checking all aspects of a client computer’s network configuration and connections. Beyond troubleshooting TCP/IP issues, it also examines a client computer’s Internet Packet Exchange (IPX) and NetWare configurations.

NetDiag is part of the Support Tools collection on the Windows 2000 operating system CD. For information about NetDiag, see Windows 2000 Support Tools Help. For information about installing and using the Windows 2000 Support Tools and Support Tools Help, see the file Sreadme.doc in the Support\Tools folder of the Windows 2000 operating system CD.

The script provides the option to run individual tests without having to learn all the switch options. It automagically outputs the test details to a text file and calls this text file up at the completion of the test. This makes it much easier to read and save the details for future use and analysis.

The front end is an hta file that provides check boxes, radio buttons and dialogue boxes for input. You have the option to select the local server or a remote DC via a text box. This script is customizable.

The storage location of the script storage of the output logfiles and diagnostic tools are modified by a const definition in the working storage section.
