Gathered informations

Windows Management Instrumentation (WMI) is the Microsoft implementation of WBEM, an industry initiative to establish standards for accessing and sharing management information over an enterprise network.

Nodes (alphabetically):

For each node, a number of informations are gathered. The informations are returned by the host's operating system.
The informations gathered for each node are presented in the Gathered informations subsection.

Note: Authentication

In "Automatic mode", to perform the WMI Scan, CHScanner will use the credentials of the account it was launched under.

In "Normal mode", to perform the WMI Scan, you will be prompted for a user name and a password that should have the permissions to query the WMI informations for the scanned computers.
The user name must be specified as: username@domain

Speed considerations

Due to the Windows implementation of WMI API, the query time-out could only be set to two minutes or "wait forever". Obviously, the second option is not acceptable if we need speed !
To speed things up you could use as discovery the TCP SYN method with 135 as parameter for port. Of course, the Scan All and Show MAC Discovered must be unchecked.

Credentials and access rights

If not scanning the localhost you should provide the credentials of an account with, at least, read rights to the WMI tree. Otherways these informations are not gathered.

For Windows XP and higher versions you can use the user principal name format, "Username@DomainName", to specify the user and domain name. For older versions use the "Domain\\UserName" format.
