When I first started using PowerShell (in version 1), I was playing around with the Get-Service command, and noticed that it had a -computerName parameter. Hmmm ... does that mean it can get services from other computers, too After a bit of experimenting, I discovered that s exactly what it did. I got very excited and started looking for -computerName parameters on other cmdlets, and was disappointed to find that there were very few. A few more were added in v2, but the commands that have this parameter are vastly outnumbered by the commands that don t. What I ve realized since is that PowerShell s creators are a bit lazy and that s a good thing! They didn t want to have to code a -computerName parameter for every single cmdlet, so they created a shell-wide system called remoting. Basically, it enables any cmdlet to be run on a remote computer. In fact, you can even run commands that exist on the remote computer but that don t exist on your own computer meaning that you don t always have to install every single administrative cmdlet on your workstation. This remoting system is powerful, and it offers a number of interesting administrative capabilities.

Remote PowerShell works somewhat similarly to Telnet and other age-old remote control technologies. When you run a command, it s actually running on the remote computer. Only the results of that command come back to your computer. Rather than using Telnet or SSH, however, PowerShell uses a new communications protocol called Web Services for Management (WS-MAN).

WS-MAN operates entirely over HTTP or HTTPS, making it easy to route through firewalls if necessary (because each of those protocols uses a single port to communicate). Microsoft s implementation of WS-MAN comes in the form of a background service, Windows Remote Management (WinRM). WinRM is installed along with PowerShell v2 and is started by default on server operating systems like Windows Server 2008 R2. It s installed on Windows 7 by default, but the service is disabled. You ve already learned that Windows PowerShell cmdlets all produce objects as their output. When you run a remote command, its output objects need to be put into a form that can be easily transmitted over a network using the HTTP (or HTTPS) protocol. XML, it turns out, is an excellent way to do that, so PowerShell automatically serializes those output objects into XML. The XML is transmitted across the network and is then deserialized on your computer back into objects that you can work with inside PowerShell. Why should you care how this output is returned Because those serialized objects are really just snapshots, of sorts; they don t update themselves continually. For example, if you were to get the objects that represent the processes running on a remote computer, what you d get back would only be accurate for the exact point in time at which those objects were generated. Values like memory usage and CPU utilization won t be updated to reflect subsequent conditions. In addition, you can t tell the deserialized objects to do anything you can t instruct one to stop itself, for example. Those are basic limitations of remoting, but they don t stop you from doing some pretty amazing stuff. In fact, you can tell a remote process to stop itself you just have to be a bit clever about it. I ll show you how in a bit. There are two basic requirements to make remoting work:

Both your computer and the one you want to send commands to must be running Windows PowerShell v2. Windows XP is the oldest version of Windows on which you can install PowerShell v2, so it s the oldest version that can participate in remoting. Ideally, both computers need to be members of the same domain, or of trusted/trusting domains. It s possible to get remoting to work outside of a domain, but it s tricky, and I won t be covering it in this chapter. To learn more about that scenario, open PowerShell and run Help about_remote_ troubleshooting.
