THIS has always traditionally been known as the Corporate site.

Please don't redefine the word is for us.

This is the Catalog site.

Trouble with the Corporate site is that they never had all of the updates. Catalog site much better coverage but still lacking in full, stand alone
executables like DirectX 9.0b.

DVader - reason your XP box isn't redirecting to V5 site may be due to lack of working Java? The V4 site downloads redirect.js to shuttle the various machines to where they need to go, but being Java, you need Java working in order to be redirected properly. V4 is only for 98/ME these days. Perhaps SP2 wiped out your Java entirely?
