MCTS Exam Managing External Clients
Terminal Services and (for that matter) have been in release since most computers were first functioning. Those two methods are experimentation and extrapolation. For particulars on using Roboserver and Roboclient, check Microsoft.com; the Enterprise Administrator exam will not test you on the particulars, so I will not discuss them here as to ease the burden of information.
When using experimentation, you take an existing server, give it a full test load of vari-ous 70-680 applications, and place it under heavy use with various users requesting different appli- cations at once. The information you derive from this experiment lets you determine where your Terminal Services server needs to be placed and what kind of hardware it will require. To aid in this process, when Microsoft released the Windows Server Deployment Kit, it included two useful tools: Roboserver ( Robosrv.exe) and Roboclient (Robocli.exe). Using these tools, an administrator can place a heavy server load without having to go through the process of creating a custom load from scratch.
With extrapolation , you examine a previously existing instance of Terminal Services and plan accordingly based on the overall deployment needs of your organization. For example, if you have a currently running server with 10 users that is at maximum capacity (which, by the way, is pretty unlikely), you would extrapolate from that existing load that an orga- nization that has 1000 users will require 100 servers to reach capacity.
In both methods, you are primarily concerned with the following:
Network load Processor overhead
Memory use
Disk usage
If any one of these server requirements becomes a bottleneck, you will have to adjust MCTS Windows 7 Configuration your server deployment method and hardware accordingly.
As mentioned earlier, one of the most important managerial processes in a complex network is making sure you have the right number of licenses?distributed in the right way, at the right time?in your Windows Server 2008 infrastructure. When using Terminal Services, users are required to have Terminal Services client access licenses (TS CALs). Client access licenses are licenses designated to a speci?c server that enable the authorization of applica-tions through Terminal Services. By default, client access licenses are available free of charge for 120 days. This means that when first installing Terminal Services, you will not have to authorize every single account.
