Perform Web-based network queries with these sites

When you want to perform network queries for troubleshooting or data collecting purposes, the standard approach has been to launch a non-graphical command line interface (CLI) in Windows or a shell prompt (such as Bash) in Linux to display the input and output of the commands you use. While this practice is undoubtedly quick and lightweight, the functionality of many networking commands has been replicated on dozens of websites which allow network administrators the same capabilities in graphical, web-based environments.

Nearly all of the networking-related command utilities have been listed and described in this blog. Some of these commands include netstat, nslookup, ping, traceroute, and whois among others. This post will show you the best and most popular websites for using these types of commands in browser-based graphical user interfaces (GUIs). These websites will be listed in alphabetical order based on domain name.

Network administration commands for Microsoft Windows and Active Directory

Administrators of Windows servers frequently utilize the graphical tools provided within the Windows Server interface to configure network parameters and administer Microsoft’s proprietary network directory service, Active Directory. These tools take the form of snap-ins for the Microsoft Management Console (MMC) and include Active Directory Users and Computers, Active Directory Sites and Services, Active Directory Domains and Trusts, the Group Policy Management Console, and others (see images below). The capabilities offered by these tools allow administrators to create, edit, and delete Active Directory objects and features such as users, computers, organizational units (OUs), domains, permissions, trusts, etc.

While there are many networking commands that are shared by diverse operating systems, Microsoft has created some that apply only to Windows. Consequently, there are many options available for Windows administrators (perhaps with Linux/Unix experience) who prefer to work in text-based, command line environments. With a little practice this approach can result in time savings and the ability to include tool functionality in scripts. For example, it can be faster to type a command or two than to click and launch the Server Manager or Administrative Tools or the other aforementioned GUI tools. Additionally, with Windows PowerShell you can script common network administration tasks making use of the graphical tools’ command line equivalents.

What follows is a listing of Windows-only commands focusing on the subject of Windows network administration. In other words, these commands can be used for the purposes of viewing, creating, and modifying network settings and the properties of Active Directory objects. You can launch them in either the Windows command prompt (cmd.exe) or in Windows PowerShell.

This page should prove especially useful for those studying to become Microsoft Certified Solutions Experts (MCSE).
