WMI Browser
To use the port scanner,
- Click on the WMI Browser button (Magnifier with a blue W letter) of the Operation toolbar
or
- Right click on a node and select the WMI Browser menu.
The browser offers the following features:
- Computer Name / IP Address: type the NetBIOS name, the FQDN or the IP address of node. By default, NetworkView enters the name or address o the currently selected node. You can use the list box to see what are the proposals.
- Namespace: the default is root\cimv2. WMI Security explains how to have access to the Management Console that displays the whole WMI structure tree and its security.
- User: the user name that will be used to access the node. Do not specify the domain in this field.
- Password: the password that will be used to access the node.
- Domain: the password that will be used together with the user name. Enter a NetBIOS name, not a DNS domain (MYDOM, and not mydom.com, for example)
Using blank values for all 3 above will use your own user credentials. This gives access to the local machine, and potentially to all machines in the domain if your are a domain administrator.
- Connect: try to connect to the local or remote node with the previous account values. If connect is successful, this button will change to Disconnect.
- Available Classes: Contains all available WMI classes on the node if connect was successful.
- Win32_: filters only the classes starting with Win32_
- Get: Choose one of the classes in Available Classes and press Get to execute the WQL query. This will return a table with all columns and rows in this class. The content of each class and it meaning can be found in the Microsoft's WMI Reference (available on their Web site).
WMI Security
The default on Windows systems is that only administrators are allowed to access the WMI Namespace from a remote node. To change this setting on a specific computer:
Run the MMC console wmimgmt.msc from a command line.
- Right click WMI Control, and then click Properties
- On the Security tab, click Security to see the allowable permissions
- Check Microsoft's help to set appropriate values.
This will change the security for this computer only.
