In the next couple of weeks Microsoft will be starting on the Service Pack 1 betaprogram for Windows Server 2003. MS is expecting to go to RTM with this inJanuary 2004.
Unlike most service pack releases, this is going to be a fairly big deal asit will introduce 3 major elements into Windows Server 2003;
X-86-64 support for the AMD's Opteron processor
IA-64 support for Intel's Itanium II CPU into the Standard Edition (it obviously already exists in Enterprise & Datacenter)
The IA-32 Execution Layer - A software technology that will roughly double the performance of 32-bit applications running on the Itanium processor family-based platforms
