15 essential open source tools for Windows admins

You might imagine that the best place to go for improving your Microsoft server-side experience is to the mothership itself. In many cases, you would be right. But the truth is there are a meaningful number of open source tools that go above and beyond what Microsoft has to offer in support of Windows Server, Exchange, SQL, and SharePoint - and for free. From networking troubleshooting to security to performance analysis, we've compiled a list of the top open source tools for your Windows-based systems. Don't see a favourite? Feel free to highlight it in the comments below.

1. Wireshark

Network troubleshooting is a real art, one that requires solid training and years of hands-on experience. But a tool like Wireshark helps ease traffic analysis, thanks to many powerful features. Just one look at this free software-based protocol analyser's colour-coding features and you'll see how its superior usability makes Wireshark a worthwhile tool for any Microsoft shop.

2. AMANDA

Admins looking to ease the pain of backing up Windows-based systems should check out AMANDA, aka Advanced Maryland Automatic Network Disk Archiver. AMANDA provides the ability for an administrator to set up a single master backup server that can support both Windows desktops and servers over the network to a variety of media, including tape drives, disks, or optical media.

3. MailArchiva

Email archiving is front and centre in Exchange 2010, thanks to the increase in compliance regulation enforcement across the industry. But for those who are not yet using Exchange 2010, MailArchiva provides a worthwhile means for bringing compliance to Exchange 2000/2003 and other mail servers, such as Postfix, Sendmail, Qmail, iMail, and Lotus Notes. MailArchiva comes in both an open source and an enterprise flavour. To see a list of features and how the two editions vary, browse the MailArchiva site.

4. Exchange 2010 RBAC Manager

Exchange 2010 RBAC Manager is a great tool for admins working with role-based access control and Exchange. RBAC Manager (aka RBAC Editor GUI) helps overcome the lack of a GUI tool to work with the new role-based administration side to Exchange, enabling admins to connect, whether or not you're a PowerShell master. The tool is written in C# and uses PowerShell behind the scenes to allow you to create and manage roles in your Exchange 2010 environment.

5. Core Configurator 2.0 for Server Core

Offering a command-line version of Windows Server 2008 and Windows Server 2008 R2 at installation was a great idea. With its light footprint, it allows a small attack surface as well. The only problem? It required administrators to crack open command-line books to configure their servers. This free tool provides a GUI method for managing tasks.

6. AutoSPInstaller for SharePoint 2010

Anyone who has ever installed SharePoint knows that the SQL databases created are a mess in terms of naming, resulting in large GUID databases titles that are completely inconsistent. In contrast, AutoSPInstaller utilises a variety of scripts to install SharePoint and makes sure database names remain clean in the process.

7. OCS Inventory

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 visualise and search.

8. UltraDefrag

UltraDefrag is a tool for Windows that can defrag system files, registry hives, and the paging file. It's continually updated to ensure improvements in performance. The tool is fully compatible with Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and all of the 64-bit editions of Windows. It's a valuable addition to any Windows environment.

Download: ultradefrag.sourceforge.net

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. This security scanner and network mapper can also be used to perform network inventory, manage service upgrade schedules, and monitor host or service uptime. It supports Windows 7, Windows Server 2008 and 2003, Windows Vista, and Windows XP SP1 and later.

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 visualisation of hosts on a network, configured in rings. Click on a host and it moves to the centre 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.

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.

Download: powergui.org

12. Performance Analysis of Logs (PAL) Tool

If you've ever had a performance problem but had no idea what metrics to collect or even how to analyse the compiled data, PAL is your friend. This open source tool helps read performance monitor counter logs and analyses them for you, using built-in thresholds that relate to the majority of your Windows products, including Exchange, SharePoint, Active Directory, and more. PAL has been tested on Windows 7 but should also run on Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, and Windows Server 2008 R2.

Download: pal.codeplex.com

13. ClamWin Antivirus

This open source antivirus solution is a valuable tool for security-minded admins. ClamWin supports Windows 7, Windows Vista, Windows XP, Windows Me, and Windows 2000/98 systems, as well as Windows Server 2008 and Windows Server 2003. The tool includes a scanning scheduler that you can use to configure appropriate scan times but does not come with an on-access real-time scanner. It also has the ability to integrate into Windows Explorer and Outlook for easy scanning.

Download: www.clamwin.com

14. Virtual Router

Virtual Router is a nifty tool that turns any Windows 7 or Windows Server 2008 R2 system into a Wi-Fi hotspot. Using Virtual Router, users can wirelessly share any internet connection (Wi-Fi, LAN, cable modem, dial-up, cellular, and so on) with any Wi-Fi-enabled device. Laptops, smartphones, netbooks, wireless printers - all can connect to Virtual Router just as they would any other access point, and the connection is completely secured using WPA2, the most secure wireless encryption.

Download: virtualrouter.codeplex.com

15. VirtualBox

VirtualBox is a must-have open source virtualisation solution for any admin seeking to run guest OSes on Windows, Linux, Macintosh, or Solaris machines. Using VirtualBox, admins can run virtual instances of a wide array of operating systems, including Windows, Linux, OpenSolaris, OS/2, OpenBSD, and even DOS. To learn more about the extent to which VirtualBox supports various operating systems as virtual machines, check out VirtualBox's guest OS wiki.
