Eventually every Citrix Administrator needs to add an additional server or servers to their farm. Adding additional servers to the farm, installing applications to them and then adding the new servers to the published applications allows XenApp to provide automatic load balancing of users of those applications across servers. XenApp uses the concept of Least Busy Server to determine which server will launch the application requested by the user.

Will a stand-alone Citrix License Server running in a Workgroup service the licensing requests for XenApp Servers running in multiple farms in multiple directory service systems? Someone asked me this question and my first thought was yes it would. But would it?

NOTE: Most people believe that XenApp can only be installed on a network that uses either Active Directory or eDirectory. That is not true. XenApp can be installed on a stand-alone workgroup computer, as well as UNIX versions for Solaris, AIX and HP-UX.
