Explanation

This scenario describes a known Citrix issue where Desktop OS VDAs configured with pass-through authentication fail to launch hosted applications. The fix is not exposed in the Studio GUI, Delivery Group settings, or standard registry edits - it requires using a PowerShell cmdlet from the Citrix Broker SDK (e.g., Set-BrokerSite or Set-BrokerMachineConfiguration) to modify a property that is only accessible programmatically. Options A (Citrix policy) and D (Delivery Group setting) do not expose the relevant configuration, and Option B (registry setting) is not the supported resolution path for this specific authentication/launch failure.
