I recently uninstalled the SQL Server 2000 Enterprise Manager Client on my laptop and started using the SQL Server 2005 Management Studio Client to manage my existing SQL Server 2000 Databases.  I'm hoping this helps me aquaint myself with SQL Server 2005 faster.  After doing so, I noticed that I couldn't open existing SQL 2000 DTS Packages.  The solution to this issue was to download/install the “Microsoft SQL Server 2000 DTS Designer Components”  from the Feature Pack for Microsoft SQL Server 2005 - November 2005.  I also found that Microsoft recently released some additional SQL Server 2005 Downloads.  See Below. 

Enjoy!!!
