Project Server 2003 Service Pack 2: Gone
Microsoft has pulled Project Server 2003 Service Pack 2 from their website. (Way back on October 27th as a matter of fact -- I apologize for my tardiness). It appears as though SP2 for the Server creates problems with Enterprise Outline Codes (see KB 909947).
Microsoft is recommending that you not deploy Service Pack 2 for the server in a production environment and, if you have and are experiencing issues, to remove it (see KB 909947).
