The WMI interface, which DomainScan and other management tools use (for instance, Microsoft Operations Manager or Microsoft System Management Server), is a powerful management interface, due to the fact that all newer Microsoft applications has a WMI-interface that can expose useful hardware and software information.




Information is retrieved by using SQL-like statements. These statements are called WQL queries (SQL for WMI), and can be used to extract information about both hardware and software from both the local and remote computers. WQL supports basic SQL – see the WMI information page at the GH Software website.

Enter the query in the Query field, and select computer(s) and namespace. Then press Run query to let DomainScan start the query on the selected computer(s).

The WMI browser can run the query on multiple computers simultaneously. See the table below for examples

Device filter	Description
*	All computers are searched
*server	All computers that have a name that ends with server are searched
?server	All computers that have a name that ends with server, and starts with a single character are searched - for instance aserver, but not a_server
pc*	All computers that have a name that starts with pc are searched
com?u?er	For instance, computers named computer, comxu3er and com1u_er are searched but not computter or computers

Select the WMI name space to search in Name space field, and type the WQL query in the Query field, and press Run.

To query the local computer, type . as computername. For any other computer, type the name of the computer.

If the query returns successfully (data is returned), the query will be remembered, and the returned data will be shown in the Data area.

Edit: Click on this label to launch an editor where WMI queries can be edited.

This is the list of name spaces that are supplied by DomainScan.
