(http://support.microsoft.com/kb/256986/ )Description of the Microsoft Windows Registry
In Microsoft Systems Management Server (SMS) version 2.0, the SMS site where the software distribution package is created is named the package source site. Additionaly, the package source site is always the site that replicates the package definition and package contents to all child sites. This replication occurs with direct child sites and with non-direct child sites. This replication model may have scalability problems for an SMS central site if the following conditions are true:
Note An example of the package definition is the package comment and the program data. An example of the package contents is a group of programs such as Microsoft Office XP Professional.
Important In this article, the new replication model is the replication model that exists after you apply the hotfix that is described in this article.

To work around the replication model that exists before you apply the hotfix that is described in this article, you must decentralize package creation. For example, to decentralize package creation, each child primary site must be the source site for its direct children.
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.The new replication model makes it possible for child primary sites to replicate package definition and package content that was created at other SMS sites. In this new replication model, the source site only replicates package definition and package content to its direct children. If those direct children are child primary sites, those direct children replicate to their children. To use the new package replication model, you must apply the hotfix that is described in this article on all sites that have or will have child sites and start the new replication model on all those sites. To start the new package replication model, you must set the value in the following registry key to 1:
The default value of this registry key is 0. A value of 0 makes the SMS package replication model the same as a site without the hotfix that is descirbed in this article. You must stop and restart the SMS Executive service or the SMS Distribution Manager component for the change to take affect.
