Windows Desktop Search for the Enterprise
I have not yet had time to look at this myself, but there's now a version of Windows Desktop Search which is targeted at the enterprise level, including SharePoint searches (WSS and SPS).
Bink pointed me at the
press release, which in turn gets you to the
download link. One thing I'm not clear on is exactly how the MSN Search toolbar (which I currently use) fits in with this. I need to pull the new tool down, which needs MSN Search to handle Outlook integration, and see how they work together.
