I have no intention in joining the number of people keen to inform you in their blogs that Microsoft have just issued a "SharePoint Administration Kit" (for both x86 and x64 with also a white paper) as I presume you've already seen the links to them in the WSS FAQ sites.

But what I think might get hidden is the fact that that Kit sneaks in a new stsadm command which you might well think ought to have been included in SP1 or as a hot fix rather than being included in a semi-official "Kit" many people probably won't bother to download.

This is a solution for a common enough problem where e-mail alerts weren't sent out if a WSS 2.0 installation had been upgraded to WSS 3.0 by the third standard upgrade method (using the 2.0 database to move the WSS 2.0 installation to another server).

This is nicely described in KB 936759 (http://support.microsoft.com/default.aspx?scid=kb;en-us;936759) which has just been updated.

"E-mail notifications for alerts are not sent when content in a migrated list or in a migrated document library changes after you perform a database migration to upgrade to Windows SharePoint Services 3.0" (ver 2.1)
