SUMMARY
When you install 64-bit editions of Microsoft SQL Server 2005, the following 32-bit versions of the following tools are installed:
 * SQL Server Management Studio
 * SQL Server Configuration Manager
 * Database Engine Tuning Advisor

When you run these tools on 64-bit operating systems, the tools run in the Windows on Windows (WOW) environment. Under certain conditions, you may experience slow performance when you run these tools.

To improve performance, run these 32-bit tools on a computer that is running a 32-bit operating system. Then, connect to a 64-bit server that is running SQL Server.



MORE INFORMATION
Notes
 * Microsoft SQL Server 2005 Business Intelligence Development Studio is not designed to run on the IA-64 64-bit architecture and is not installed on IA-64-based servers. SQL Server 2005 Business Intelligence Development Studio is the 32-bit development environment for business intelligence solutions.
 * If you have 64-bit (x64) management tools, SQL Server Integration Services, and SQL Server Notification Services installed as part of a 64-bit instance of SQL Server 2005, you cannot install 32-bit versions of the same components in a side-by-side configuration.
