I got this issue when I want to perform change farm on one of my Citrix XenApp farms. The installed version is Citrix XenApp 5 for Server 2008. I have not encountered any issue before while using Windows Server 2003, so I believe this issue is somehow related to the differences between those 2 Windows versions, well, particularly the UAC.  Issues : CHFARM utility failed in the middle, with below error : Troubleshooting   It is due to UAC permission, it blocks CHFARM utility from properly running because it ran in Admin Approval Mode. Resolution : Go to Start > run, and type secpol.msc    When you see this UAC permission control screen, choose I want to complete this action option, and press Ctrl + Alt + End as requested after that.  Press Continue   Browse to Security Options as below  Search for this option : User Account Control : Rul all administrators in Admin Approval Mode  Right click at the option, and choose Properties
