Recent WSS3 update hangs, then kills your site.

I approved an update recently.  KB932091.

This update got most of the way through the install, hung and then I got an error on sharepoint.   The error, when browsing to the site, included blah blah blah blah blaaaaah is not accessible to missing Windows Internal Database signatures.

This issue, from what I can tell, only seems to affect SBS2003 R2.

For those having the issue, go here, and then extract the patch – using the /extract statement, and force the install by double clicking the dw20w.msp file.   It takes a while (up to an hour and a half), but worked for me!  (If you don’t extract the package, it will tell you you already have it!)

Hope this helps someone!
