By default, when using Remote PC Access in XenDesktop 7.0, console session on the physical machine can be started to assign multiple users to the same Remote PC Access desktop, provided they conform to the relevant assignment policies. This gives all these users the ability to start remote sessions on the machine.

Important: This how-to will affect machines that are in Remote PC Access catalogs. For more information on setting up Remote PC Access in XenDesktop, see Remote PC Access topic in eDocs.
