I know I am just a lowly developer but I due use some administrative tools and I have loved for a long time and continue to use the Sysinternals set of tools. They have just opened up a new way to access there tools from there blog entry (with way too long of a title so I shortened it) Introducing Sysinternals Live Beta:
Sysinternals Live: We're excited to announce the beta of Sysinternals Live, a service that enables you to execute Sysinternals tools directly from the Web without hunting for and manually downloading them. Simply enter a tool's Sysinternals Live path into Windows Explorer or a command prompt as \\live.sysinternals.com\tools\<toolname> or view the entire Sysinternals Live tools directory in a browser at http://live.sysinternals.com.
I love it now I can download or just run the apps in a batch file!
