Here's how to install Intel Active Monitor on Windows Server 2003.
Double-click the file downloaded from Intel.
It extracts to the user temp directory.
Locate the directory (named something like pft64~tmp with current timestamp) and make a copy of it.
Exit installer (the installer will delete the extracted files).
Open that copied directory and navigate to the SMBUS directory.
Run the setup which will downgrade the SMBUS driver.
When that completes, navigate up one level and re-run the setup.
The installer seems to not like the newer version of the driver when running in W2K3 Server.
