Zach Rosenfield (a Program Manager on the SharePoint Team) posted an announcment introducing the SharePoint Administration Toolkit. This promises to be a great resource for administering your MOSS and WSS v3.0 deployments. The initial version of the toolkit contains a couple of useful administrative tools, including the Batch Manager, which allows you to schedule bulk operations against site collections in a SharePoint farm, and a new command to the STSADM command-line utility called "updatealert" which will refresh all alert URLs in a specific site collection, which is important if you change the URL of a web application or after an upgrade. A full whitepaper describing the toolkit can be found here.
Check out Zach's post of you want to have a good understanding of what the toolkit addresses and the features it contains. The toolkit is available for download for both x86 and x64 SharePoint deployment configurations.
Enjoy! I know I will! :-)
