Ready Internet/Intranet School Management System on .NET

I am looking out for a School management system which is both intranet based as well as web based platform. PLEASE NOTE THAT I AM LOOKING AT A READILY AVAILABLE SOLUTION and don’t want to create from the start. If available please send me the link for the DEMO of the product. The web part will be installed and running in the internet and the Intranet based application will be installed on a standalone system, but both applications should inter related.
