Microsoft added this note to the MS15-027 post
V2.0 (March 16, 2015): To address a connectivity issue with update 3002657 when installed on supported editions of Windows Server 2003, Microsoft released update 3002657-v2 for all supported editions of Windows Server 2003. Customers who have not already installed the 3002657 update should install update 3002657-v2 to be fully protected from this vulnerability. To avoid the possibility of future detection logic problems, Microsoft recommends that customers running Windows Server 2003 who have already successfully installed the 3002657 update also apply update 3002657-v2 even though they are already protected from this vulnerability. Customers running other Microsoft operating systems are not affected by this rerelease and do not need to take any action. See Microsoft Knowledge Base Article 3002657 for more information.
