For each virtual desktop created using Machine Creation Services (MCS), an Identity Disk is required, which is 16 MB in size. To calculate the total storage space needed for 500 virtual desktops, you multiply 16 MB by 500, resulting in 8000 MB. Converting 8000 MB to GB, you get 8 GB. Therefore, the minimum storage space needed for the Identity Disks in this environment is 8 GB.
When setting up a high availability scenario using a Windows-based identical License Server for Citrix, it is crucial to ensure that the second License Server has a different hostname. This avoids conflicts on the network, as identical hostnames can cause significant issues.
The possible reason client drives are not mapped when a user launches the desktop is that loopback processing is not enabled. In this scenario, the `Auto connect client drives` setting is a user setting, and for a Group Policy Object (GPO) linked to an Organizational Unit (OU) containing computer objects to apply user settings, loopback processing must be enabled. Loopback processing allows user policies to be applied to computer objects, which ensures that user settings in the GPO linked to the computer's OU are correctly applied. Without loopback processing, user settings from a GPO linked to the computer's OU will not take effect.
