If you’re using SCOM 2007 then you’ve surely been on the MS System Center Catalog web page. It’s a pain to use, not nearly as bad as the new TechNet download page, but it’s horrible anyway. The OpsMgr team is now placing Microsoft management packs on the public TechNet site. You can download the operating system technologies (Base OS, DNS, DHCP, etc) and the other server products (Exchange, SQL, etc) without having to endure drop-down list box reset hell.
