I’ve posted this as an update on my December Cumulative Update article, but think it worth posting afresh too. Thanks Shazeb for bringing to my attention.
If you are running MOSS with Project you should NOT load the December CU for MOSS as it has been withdrawn because of a search issue that is resolved in the February CU.
For full details of the issue please see http://blogs.msdn.com/joerg_sinemus/archive/2009/03/26/moss-december-cu-960011-is-not-available-anymore.aspx and for details of the Feb CU see http://blogs.msdn.com/brismith/archive/2009/03/13/project-server-2007-cumulative-update-for-february-2009.aspx
Is the Dec MOSS 960011 the right number? I have it as 959637 @
Both are right :). 960011 is the rolled up Office Servers one that contains Project, MOSS etc.
