Thanks to my MVP status I got a free MSDN subscription that's packed with Visual Studio 2005 Team Suite. The installation however still lacked the Database Professional part. After some msn-ing with Gabriël I could also download the extra addon for that as well.

You can find the download here: Visual Studio 2005 Team Edition for Database Professionals Add-on for Visual Studio 2005 Team Suite Edition.

Grz, Kris.
