The Windows System Resource Manager (WSRM) is a tool that you can install and use no matter which configuration of Windows Server 2008 you use. When you’re working in a workgroup setting, the main purposes for WSRM are to monitor Terminal Services connections and to manage resource usage by applications. In a domain environment, WSRM also helps you keep tight control over how the system and users work with resources. Using this tool helps you create an environment where everyone gets their fair share of resources. Of course, you can weight the usage depending on the criticality of the resource need.
To use WSRM, you must install the Windows System Resource Manager feature. When you check the Windows System Resource Manager feature, you see the Add Features Wizard dialog box, telling you that you must install the Windows Internal Database feature as well. Click Add Required Feature to add this feature, if you haven’t already installed it.
After you install WSRM, you see a new Windows System Resource Manager entry in the Administrative Tools folder. Opening the Windows System Resource Manager console displays the Connection to Computer dialog box, where you can choose the local computer or another computer on the network to manage. This section uses the local computer as an example, but the techniques shown work with other Windows Server 2008 computers as well. Choosing a connection displays the resources for the computer you select.
The functionality provided by WSRM is new for Windows Server 2008. WSRM is such a useful console that you want to consider using it for heavily loaded systems or for networks that tend to become overwhelmed.
