“Remote Desktop Connection Manager” is a MMC snap-in tool of Windows Server 2008 R2 for managing “in-box VDI” solution. This post explain how you can specify various RDP settings for virtual desktops published using this tool. You can specify different set of RDP settings for each type of VDs (Personal and Pooled). To modify RDP settings for "Personal Virtual Desktops," expand "RD Virtualization Host Servers" node, select "Personal Virtual desktops" and then select "Properties" from actions. To modify RDP settings for pooled VDs, select pool node under “RD Virtualization Host Servers” node, then select "Properties" from actions. This allows you to change RDP property for pool selected. For more than one pool, you’ll have to change RDP settings for each pool of VDs from respective nodes. For common RDP settings there’s a "Common RDP Settings" property tab with dedicated UI controls for each of setting. “Custom RDP Settings” tab allows you to specify advanced RDP settings which’re not modified frequently. Enabling optimal user experience: By default, VDs published through this tool are tuned for performance. For e.g., with default RDP settings, users willn’t be able to see wallpaper on their VD. To enable optimal audio/visual user experience, add RDP settings under "Custom RDP settings" tab (see pic). With the settings, RDP connections to VMs require higher network bandwidth compared to default settings. Therefore admin should enable these settings taking into account available network bandwidth and desired user experience.
