WbemAuthenticationLevelEnum (Windows)

WbemAuthenticationLevelEnum

The WbemAuthenticationLevelEnum constants define the security authentication levels. These constants are used with SWbemSecurity and in moniker connections to WMI.

The WMI scripting type library, wbemdisp.tlb, defines these constants. Visual Basic applications can access this library.

Script languages must use one of the following:

The short name. For example, for WbemAuthenticationLevelPktPrivacy use "PktPrivacy".


strComputer = "RemoteComputer"
Set objWMIServices = GetObject("WINMGMTS:" _
    & "{authenticationLevel=pktPrivacy}!\\" _
    & strComputer & "\ROOT\CIMV2")

Windows Script Host (WSH) XML file format in the script. For example, this means that the script can use the WbemAuthenticationLevelPkt constant directly.

The following WSH script sets the authentication level. To run the script, save the text in a file with a .wsf extension.

<?xml version="1.0" encoding="US-ASCII"?>
<job>
<reference object="WbemScripting.SWbemLocator"/>
<script language="VBScript">
    set service = GetObject("winmgmts:")
    ' Following line uses a symbolic 
    ' constant from the WMI type library
    service.Security_.authenticationLevel = _
        WbemAuthenticationLevelPktPrivacy
</script>
</job>

For more information, see Using the WMI Scripting Type Library.

The following values can be used to set the authentication level.

Constant/value	Description
WbemAuthenticationLevelDefault 0 (0x0)	Short name: Default WMI uses the default Windows Authentication setting.
WbemAuthenticationLevelNone 1 (0x1)	Short name: None Uses no authentication.
WbemAuthenticationLevelConnect 2 (0x2)	Short name: Connect Authenticates the credentials of the client only when the client establishes a relationship with the server.
WbemAuthenticationLevelCall 3 (0x3)	Short name: Call Authenticates only at the beginning of each call when the server receives the request.
WbemAuthenticationLevelPkt 4 (0x4)	Short name: Pkt Authenticates that all data received is from the expected client.
WbemAuthenticationLevelPktIntegrity 5 (0x5)	Short name: PktIntegrity Authenticates and verifies that none of the data transferred between client and server has been modified.
WbemAuthenticationLevelPktPrivacy 6 (0x6)	Short name: PktPrivacy Authenticates all previous impersonation levels and encrypts the argument value of each remote procedure call.
