When the Microsoft System Center Configuration Manager 2007 console is running on a server with a connection to the Internet, the top node in the console automatically connects to the Microsoft TechNet site to display the System Center Configuration Manager TechCenter. In Configuration Manager 2007 SP1, you can modify the registry to prevent the console from contacting the Internet to display the TechCenter page.
The information in this topic applies only to Configuration Manager 2007 SP1 and later.
To prevent the System Center Configuration Manager console from downloading the TechCenter home page
In a registry editor, locate the key HKLM\Software\Microsoft\ConfigMgr\AdminUI.
Create a new DWORD value DisableHomePage.
You do not need to set any data for the DisableHomePage value; if the value exists, the console will not attempt to connect to the TechCenter home page.
