Important
The Preparation Tool requires an Internet connection in order to download and install any required applications. For example, if Forefront TMG is running behind a proxy server, you might need to configure the proxy settings to enable Forefront TMG server access to the Internet.
If these applications are not already installed on your computer, the Preparation Tool downloads and installs them.
Note
After running the Preparation Tool, you must reboot the computer before installing Forefront TMG.
To run the Preparation Tool
On the Installation Type page, select the required installation type option:
Forefront TMG services and Management.
Forefront TMG Management only
Enterprise Management Server (EMS) for centralized array management
The Preparation Tool downloads and installs the prerequisite applications, according to the selected Forefront TMG installation type.
On the Preparation Tool’s Preparation Complete page, select Launch Forefront TMG Installation Wizard and then click Finish.
