Just checked the links and they are all now live – so updated my list. One clarification on a the specific KBs and downloads for Project Server and the SharePoint/Microsoft Office SharePoint Servers. The Office Server hotfix I list is the complete package that includes Project Server 2007 April CU too. This is KB 968851 and is called SharePoint Server 2007 cumulative update package (MOSS server package): April 30, 2009. There is another hotfix that I know Christophe and Scott Wagner list in their articles – and this is KB 968859 - Microsoft Office SharePoint Server 2007 hotfix package (Coreserver.msp): April 30, 2009. This one does not contain the Project Server fixes – so very useful if you already loaded the Project Server CU before the combined one was available.
