Whats new? well these bits are!
Clustering
A new event log event has been created to address certain situations in which the Cluster service account becomes excessively restricted by domain policy.
Data access components
XmlLite is new with Windows Server 2003 SP2. XmlLite is a fast, low-level, native XML parser with a small memory footprint.
Distributed systems
New options have been added to the Dcdiag.exe Domain Name System (DNS) tests.
File systems
Icacls.exe is an upgrade of the Cacls.exe tool in Windows Server 2003 SP2, and can be used to reset the access control lists (ACLs) on files from Recovery Console, and to back up ACLs. Also, unlike Cacls.exe, Icacles.exe correctly propagates the creation of inherited ACLs and changes to them.
