I had the need to read some data from a couple of volumes formatted under Linux with the EXT2 and EXT3 file systems. The challenge was that I needed to access them from a Windows machine. Windows does not natively support reading these file systems, unfortunately.
So a quick Google search later, I stumbled upon a great utility called Explore2fs - It's written by John Newbigin and does a fabulous job of providing access to data that resides on these file systems. I was easily able to drag and drop the files from the EXT3 partition I had to my Windows Server 2003 drive. The coolest part - it's a stand alone executable - no install, no registry settings, no mess. Just double-click and go. Explore2fs supports Win95, Win98, WinME, NT4, W2K and Windows XP. It worked fine for me under Windows Server 2003 as well...
Here is the link to John's site for Explore2fs - http://uranus.it.swin.edu.au/~jn/linux/explore2fs.htm.
