SCCM Installation Prerequisites tool
A great tool has been released by Microsoft to aid administrators with the installation of System Centre Configuration Manager (SCCM). The idea of this tool, is that you run it prior to installing SCCM and it will check if you have the correct prerequisites in place and also install them if required.
You can install all the prerequisites for a Central Primary site, Primary or Secondary Sites, as well as other site system roles. (ie Management Point, Application Catalog, Distribution Point, Enrollment Point etc)
Thought this was a great tool and worth sharing. Tool is available for download here, directly on the Microsoft Site
