Hello Scott,
When you access Time Synchronization from Options of Lookout, you will not see any computers immediately. You will have add the server computer to which you want the client to be synchronized with. So in the client computer running Lookout, go to Options>Time Synchornization and add the server computer name to it. This way you can make all the clients to be synchronized to the server computer.
