Time to hoard the SMS Installer installation executable?
It seems the only way to download the SMS Installer executable these days is to download it from a cached page.
Cached page
Only a short time ago, it was freely downloadable from the Microsoft web site from this page:
http://www.microsoft.com/technet/sms/20/downloads/tools/installer.mspx
..but, not anymore. If you have it, hold on to it. It could be the only thing worth anything should the economy not recover. I can see a day where a copy of SMS Installer could buy you just about anything in the new market.
