Implementing multiple policies
You can use many different policies to adapt XenDesktop to users' requirements based on their job function, physical location, or connection type. For example, you may want to put restrictions on user groups that work with sensitive data. You can create policies that prevent users from saving files to their local media. However, if users in the same group need access to their local media, you can create a different policy just for those specific users. You would then configure priorities on the two policies to control which one takes precedence. When implementing multiple policies, you will need to ascertain how to prioritize them, how to create exceptions, and how to view the resultant policy when there is a conflict. It is a good idea to create an environment in a Proof-of-Concept lab setting to test your policies before rolling them into production.
Also, Citrix policies interact with Windows operating system policies and some Windows policies take precedence...
