ClientIP Property

Exchange Server 2003

The ClientIP property indicates the TCP/IP address of the messaging client that originally submitted the message. The ClientIP property is read-only.

Applies To

The ClientIP property is a member of the Exchange_MessageTrackingEntry Class.

Instance Path

The ClientIP property appears on instances of the \\COMPUTERNAME\ROOT\MicrosoftExchangeV2:Exchange_MessageTrackingEntry class.

MOF Syntax

[read] string ClientIP;

Qualifiers

This property has no qualifiers.

Selecting Instances Using VBScript

The following example shows how to retrieve a list of Exchange_MessageTrackingEntry instances, and the ClientIP property, using the ExecQuery method.


'===============================================================
' Name:      ShowExchange_MessageTrackingEntry_Query_ClientIP
' Purpose:   Display each Exchange_MessageTrackingEntry found for the
'            specified Exchange server, and show the ClientIP
'            property for each Exchange_MessageTrackingEntry
'            instance. Only log entries created within the
'            number of hours specified are displayed.
' Input:     strComputerName [string] the computer to access
'            intHoursToShow [integer] the number of hours before the
'            present time for which log entries will be shown.
'            intUTCOffset [integer] Local time offset from UTC
' Output:    Displays the KeyID and ClientIP properties
'            for each Exchange_MessageTrackingEntry created
'            within the specified time.

'===============================================================
' IMPORTANT: This script may take a very long time to execute when run
'            on a heavily used Exchange server, or when a very long
'            intHoursToShow is given. This script uses the ExecQuery
'            programming style, and gives a lower limit to the
'            TimeLogged property. It is recommended that applications
'            specify lower and upper bounds for the TimeLogged
'            property to improve performance.

VBScript Example

The following example shows how to retrieve a list of Exchange_MessageTrackingEntry instances, and how to retrieve the ClientIP property.


'===============================================================
' Name:      ShowExchange_MessageTrackingEntry_ClientIP
' Purpose:   Display each Exchange_MessageTrackingEntry found for the
'            specified Exchange server, and show the ClientIP
'            property for each Exchange_MessageTrackingEntry
'            instance.
' Input:     strComputerName [string] the computer to access
' Output:    Displays the KeyID of each Exchange_MessageTrackingEntry and
'            the ClientIP properties.
'
'===============================================================
' IMPORTANT: This script may take a very long time to execute when run
'            on a heavily used Exchange server, because the script
'            lists information about all message transfers recorded
'            in the message tracking logs. The GetInstances style
'            of access used in this script causes the WMI provider
'            to enumerate all log entries. To improve the performance
'            of scripts using Exchange_MessageTrackingEntry instances,
'            it is recommended you use WMI ExecQuery, and restrict
'            the results range with the TimeLogged property.
