The Open Ports page is not available if the Windows SNMP protocol is not installed on:
The open communication ports on a Windows machine are not necessarily in use. They may be the inadvertent consequence of a now-stopped service or some other application, or they may have been opened by a virus.
The Open Ports page on the Network drilldown summarizes the status of all the communication ports on the machine under diagnosis. Each row in the table (grid) represents an open port, and the columns in the grid display the properties associated with it.
To open the Open Ports page
Click Network | Open Ports.
Note: In the Open Ports page, the term local refers to the Windows machine under diagnosis. Remote refers to any machines connected to a port on the diagnosed (local) machine.
