Hello Otto,

You can use a VBA-Script => save the Code to : PingAll.vbs
Call from Command-Line, or use Winexec : CSCRIPT pingall.vbs >> results.txt

Code: Select all  Expand view

OPTION Explicit
DIM cn,cmd,rs
DIM objRoot
DIM intFailed, intSucceeded
DIM strPing

set cmd = createobject("ADODB.Command")
set cn = createobject("ADODB.Connection")
set rs = createobject("ADODB.Recordset")

cn.open "Provider=ADsDSOObject;"
cmd.activeconnection = cn

' call from Command-Line : CSCRIPT pingall.vbs >> results.txt  
' -----------------------------------------------------------

' Used to get the default naming context. e.g. dc=wisesoft,dc=co,dc=uk
set objRoot = getobject("LDAP://RootDSE")

' Query for all computers in the domain
' -------------------------------------
cmd.commandtext = "<LDAP://" & objRoot.get("defaultNamingContext") & ">;(objectCategory=Computer);" & _
          "dnsHostName;subtree"
'**** Bypass 1000 record limitation ****
cmd.properties("page size")=1000

set rs = cmd.execute

intFailed = 0
intSucceeded = 0

' Ping all computers in the domain
while rs.eof <> true and rs.bof <> true
   strPing = ping(rs("dnsHostName"))
   IF LEFT(strPing,2) = "OK" then
      intSucceeded = intSucceeded + 1
   ELSE
      intFailed = intFailed + 1
   END IF
   wscript.echo rs("dnsHostName") & " : " & strPing
   rs.movenext
wend

cn.close

wscript.echo "Finished (" & intSucceeded & " Succeeded, " & intFailed & " Failed)"

' Function to ping a computer
private function ping(byval strComputer)
DIM Status,objPing, ObjPingStatus
status = "Error"
Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}")._
ExecQuery("select * from Win32_PingStatus where address = '" & _
strComputer & "'")
For Each objPingStatus in objPing
   If IsNull(objPingStatus.StatusCode) then
      status = "Failed"
   elseif objPingStatus.StatusCode<>0 Then
      status = "Failed (" & getPingStatus(objPingStatus.StatusCode) & ")"
   else
      status = "OK (Bytes= " & objPingStatus.BufferSize & _

Next

ping = status

end function

' Function to convert the status code into a useful description
private function getPingStatus(byval statusCode)

Another Version : save and call as => ????.vbs

Code: Select all  Expand view

On Error Resume Next

Const ADS_SCOPE_SUBTREE = 2
Const ADS_SECURE_AUTHENTICATION = 1

Set objConnection = CreateObject("ADODB.Connection")
Set objCommand =   CreateObject("ADODB.Command")
objConnection.Provider = "ADsDSOObject"
objConnection.Open "Active Directory Provider"
Set objCommand.ActiveConnection = objConnection

objCommand.Properties("Page Size") = 1000
objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE

objCommand.CommandText = _
    "SELECT CN FROM 'LDAP://dc=fabrikam,dc=com' WHERE objectCategory='computer'"  
Set objRecordSet = objCommand.Execute

objRecordSet.MoveFirst

Do Until objRecordSet.EOF
    strComputer = objRecordSet.Fields("Name").Value

    Set objShell = CreateObject("WScript.Shell")
    strCommand = "%comspec% /c ping -n 3 -w 1000 " & strComputer & ""
    Set objExecObject = objShell.Exec(strCommand)

    Do While Not objExecObject.StdOut.AtEndOfStream
        strText = objExecObject.StdOut.ReadAll()
        If Instr(strText, "Reply") > 0 Then

            strComputer = "WinNT://" & strComputer

            Set objDSO = GetObject("WinNT:")
            Set objComputer = objDSO.OpenDSObject _
                (strComputer, strUser, strPassword, _
                    ADS_SECURE_AUTHENTICATION AND ADS_USE_ENCRYPTION)

            ' =====================================================================
            ' Insert your code here
            ' =====================================================================

            objComputer.Filter = Array("User")
            For Each objUser in objComputer
                Wscript.Echo objUser.Name
            Next

            ' =====================================================================
            ' End
            ' =====================================================================

        Else
            Wscript.Echo strComputer & " could not be reached."
        End If
    Loop
    objRecordSet.MoveNext
