First of all here are the KB articles. It's a long list, but there's links in there to an introductory presentation/webcast on SharePoint 2003, what you can't install in the same server as SharePoint, lots on installation troubleshooting and backup and restore issues. MS has put a lot of crucial stuff up there, that's why I'm making sure I link directly to them.

Here's the 2 new SPS2003 Web Parts sent to me by Daniel McPherson, SPSFAQ090252 - 'I want to go' and search web parts for SharePoint 2003

The SharePoint Pricing can be downloaded in this zip file of the Word document.

Here's a script to delete all parts of a failed workspace creation on SPS2001, but it's useful for deleteing corrupt workspaces too. Download the ZIP here. Thanks to Graham Watkins for sending me that.

I'm sure a lot of people have heard of this bug that affects installations of WSS done after November 24th along with Windows Small Business Server 2003 (Standard and Premium editions) or upgrades of Windows Small Business Server 2003. The gist is you have to change the date on your sever to before November 24th but after May 24th to stop the DLLs messing up. There is more info here on this SBS site. Thanks to Adam Mucaulay for letting me know about this.

This is one to be careful of if you are making SharePoint accessable via the web, make sure you have a robots file to restrict certain paths from spiders crawling from search engines like google, your SharePoint security could be compromised by a hacker just searching for the following in Google: "/_layouts/settings.htm/" (with quotes). They can't do any real harm because none of the links work, but still...

There are changes that have to be made in your brower settings before you see what happens, read the following for more details:
bug in how the authentication mode works with the web-based administration page.
Microsoft SharePoint May Let Remote Users Access Protected Pages Without Authenticating.

Finally, want to try WSS free for 30 days? Go here: http://www.sharepointtrial.com/default.aspx for details.

Oh, and you can download the SPS2003 SDK from here and WSS from here.
