This section discusses significant changes to the software distribution functionality in Microsoft System Center Configuration Manager 2007.
Advertisements Not Replicated to Secondary Sites
In SMS 2003, all advertisement information was sent to both secondary and primary sites because Legacy Clients could be assigned directly to secondary sites. However, Configuration Manager 2007 does not use Legacy Clients and all clients can be assigned only to a primary site.
Because of this, Configuration Manager no longer replicates advertisement information to secondary sites, resulting in significant performance improvements and savings in network bandwidth.
