At ArcGIS 10, dockable windows based on Windows Presentation Foundation (WPF) technology have replaced several windows throughout the system, such as the attribute table window in ArcMap. The shadows and dock hints for these dockable windows are rendered using WPF bitmap remoting within Remote Desktop Services (RDS) and Citrix XenApp environments, which increases server-side CPU utilization and network bandwidth usage. This can reduce performance, particularly over bandwidth-limited links.
Instructions provided describe how to turn off the dockable window shadows and dock hints when using ArcGIS Desktop 10 SP1 in an RDS or Citrix XenApp environment.
A registry key was added to ArcGIS 10 (Desktop, Engine, Server) Service Pack 1 (SP1) to turn off the dockable window behavior to improve rendering performance of WPF-based windows for RDS and Citrix XenApp environments.
Warning: The instructions below include making changes to essential parts of your operating system. It is recommended that you backup your operating system and files, including the registry, before proceeding. Consult with a qualified computer systems professional, if necessary. Esri cannot guarantee results from incorrect modifications while following these instructions; therefore, use caution and proceed at your own risk.
Note: It is very important to determine whether the server is 32-bit or 64-bit to set the key in the HKEY_LOCAL_MACHINE hive. The registry key location is different for these operating systems.
