The Turn on Remote Desktop IP Virtualization machine setting should be configured correctly. This policy setting specifies whether Remote Desktop IP Virtualization is turned on. By default, Remote Desktop IP Virtualization is turned off. If you enable this policy setting, Remote Desktop IP Virtualization is turned on. You can select the mode in which this setting is applied. If you are using Per Program mode, you must enter a list of programs to use virtual IP addresses. List each program on a separate line (do not enter any blank lines between programs). Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Application Compatibility\Turn on Remote Desktop IP Virtualization (2) KEY: HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\TSAppSrv\VirtualIP\EnableVirtualIP
