I've deployed Windows Server 2012 VDI in my test lab. I can create a collection of personal desktops and give users access to it. However, I cannot find a way to see how many desktops in the pool were already assigned. I also cannot find a way to find which users were already assigned a personal desktop, and I cannot remove assignments that already exist.
In Windows Server 2008 R2 it was possible to look at msTSPrimaryDesktop attribute of AD user account to find whether the user has a personal desktop assigned, as well as clear it to remove the assignment. However, in Windows Server 2012 this attribute is not populated. In addition, I cannot find 'Personal Virtual Desktop' tab in AD account properties which is mentioned in several TechNet articles.
How should I manage personal desktop assignments in Windows Server 2012?
