Policy settings reference 编辑
Policies include settings that are applied when the policy is enforced. Descriptions in this section also indicate if more settings are required to enable a feature or are similar to a setting.
Quick reference
The following tables list the settings that you can configure within a policy. Find the task that you want to complete in the left column, then locate its corresponding setting in the right column.
A full listing of all policy settings is available in .CHM (Compiled HTML) format and .CSV format. These files are available in the \program files\citrix\grouppolicy folder on the server where the broker (delivery controller) is installed. You can also download the latest version of the policy settings by clicking here.
