FOSS Programs for NT Servers

While my primary job nowadays has nothing to do with NT servers (other than using an XP laptop), I still have various Windows servers that I have to support once in a while, and when I do, there is always something inevitably screwy on them, so I’m always looking for tools that help do “simple” things like backup drivers and help clean up system partitions.

For these types of things, three tools come to mind.

• SpaceExplorerEx: finds space hogs on a hard drive
• WinDirStat: also finds space hogs (but with a more colorful GUI)
• DriverBackup! 2: backs up drivers for later

I’m kicking around the idea of creating a wiki where people could post FOSS tools that they’ve used for servers. Any ideas others have on the subject would be welcome.
