Win32_PerfRawData_PerfNet_Server class
The Win32_PerfRawData_PerfNet_Server raw performance data class provides raw data from performance counters that monitor communications using the WINS Server service.
This class represents the Server object in System Monitor. The original data source is the PerfNet performance library. The corresponding formatted data class is Win32_PerfFormattedData_PerfNet_Server. Data is dynamically provided for this class from the performance library object by the WmiPerfInst provider.
Windows Server 2003 and Windows XP: WMI data for this class is supplied by the Performance Counter Provider.
The following syntax is simplified from MOF code and shows all inherited properties, including the Frequency and Timestamp properties required for class display in System Monitor. For more information about required property qualifiers, see Property Qualifiers for Performance Counter Classes. For more information about CounterType values, see WMI Performance Counter Types.

Remarks
All classes derived from Win32_Perf are designed to be used with a refresher object. For more information about how to create and use a refresher object in C++, see Accessing Performance Data in C++. For more information about how to create and use a refresher object using scripts, see Refreshing WMI Data in Scripts.
The performance class and property qualifiers determine how to interpret the class data. For more information, see Class Qualifiers for Performance Counter Classes and Property Qualifiers for Performance Counter Classes.
