If you need a cool tool for locating all the devices connected to your network and what software and hardware you have installed on your systems, then OCS-NG is the one for you. It requires you install the OCS client inventory agent on your systems; you can then pull all that information into a repository that's easy to visualize and search.

Essential open source Windows admin tool No. 9: Nmap for Windows

Originally a Unix-only tool, Nmap for Windows has been an important security resource for Windows shops for more than 10 years.

It supports Windows 7, Windows Server 2008 and 2003, Windows Vista, and Windows XP SP1 and later.

Essential open source Windows admin tool No. 10: Zenmap

Zenmap is a cool tool for mapping a topology of devices connected to your network. This security scanner works off of Nmap, providing an interactive, animated visualization of hosts on a network, configured in rings. Click on a host and it moves to the center of your network topology, giving you the ability to easily trace the host's various connections. With Zenmap, information regarding potential vulnerabilities becomes that much easier to pinpoint, ensuring your firewalls and routers are working correctly.

Essential open source Windows admin tool No. 11: PowerGUI

It's no secret that PowerShell is taking the Windows world by storm. It feels like a retro pleasure for many long-term admins who remember the command-line days. But for others, banging on the command line to administer systems can be a pain.

Those looking for a more graphical means of tapping into PowerShell should check out PowerGUI, a free graphical user interface and script editor for PowerShell. More valuable perhaps is the community built around PowerGUI, with its vast store of contributed scripts and libraries for administering your fleet.
