During the installation process on a test Windows 2008 server, which is on a internal IP address, SCCM 2007 wants to download updated versions of some components. This can result in an error message that reads
Failed to download prerequisite component.
This results in a message in the log
C:\ConfigMgrSetup.log that reads:
<05-22-2012 08:36:05> External files directory is C:\sccmdownload
<05-22-2012 08:36:05> Checking for component updates...

There is already a winhttp proxy set through
netsh, but that doesn't seem to help. Many posts on technet and other search results indicate that running the downloader separately from the installer can help
C:\Microsoft System Center Configuration Manager Server 2007 R3 SP2\SCCM 2007 w SP2\SMSSETUP\BIN\I386>SETUP.EXE /download c:\sccmdownload
But for me, this results in the exact same error message in the log.
