RE: [logs] FW: Windows Auditing question

Tina's statement is correct, but I think Bruno's problem is slightly
different- he wants to filter a single machine's log on an insertion
string.

Using WMI, you can directly access an event's insertion strings,
enabling the query you're asking about.  Here's some sample VBScript
that will get you the first 90% of the way, the second 90% is up to you.
No, I won't give any further programming assistance 'cause it took me
too long to figure this out myself :-)

'security
On Error Resume Next
strComputer = "."

Set objWMIService =
GetObject("winmgmts:{impersonationLevel=impersonate,(security)}\\" &
strComputer & "\root\cimv2")

Set colItems = objWMIService.ExecQuery("Select * from Win32_NTLogEvent
Where Logfile='Security'",,48)

For Each objItem in colItems
    Wscript.Echo "Timestamp: " & objItem.TimeGenerated
    Wscript.Echo "User:      " & objItem.User
    Wscript.Echo "Computer:  " & objItem.ComputerName
    Wscript.Echo "Type:      " & objItem.Type
    Wscript.Echo "Source:    " & objItem.SourceName
    Wscript.Echo "Category:  " & objItem.CategoryString
    Wscript.Echo "Event ID:  " & objItem.EventIdentifier
    Wscript.Echo "Description:"

    for each insertString in objItem.InsertionStrings
	WScript.Echo "     " & insertString
    next

    Wscript.Echo

you're in a windows NT environment, right?  and clearly there's a domain
involved.  it sounds like you've enabled login auditing on the primary
domain controller.  unfortunately, on an NT 4 domain, the events for
user login and logout are only recorded on the local workstations, not
on the domain controller.

so you can either grab logs from all your workstations, or upgrade to
win2k that records domain logins at the domain controller.

i'll see if i can find a reference to this, but i've got to go to a
meeting...
