Vista - Convert hostname text file to IP text file

I'm trying to convert a list of servers names from hostnames to IP
addresses. Can someone tell
me whats wrong with my script? thanks


Const FOR_READING = 1
Const FOR_APPENDING = 8


Dim WshShell, objInputFile, objOutputFile
Dim objNetwork, IP
Dim RegEx, WSH, strTarget, arrTargets

Set RegEx = New RegExp

Set WSH = CreateObject("WScript.Shell")
Set WshShell = WScript.CreateObject("WScript.Shell")
Set FileSys = CreateObject("Scripting.FileSystemObject")
Set objNetwork = WScript.CreateObject("WScript.Network")



Set objInputFile = FileSys.OpenTextFile("c:\hostnames.txt",
For_Reading)
Set objOutputFile = FileSys.CreateTextFile("c:\IP.txt", For_Appending)

arrServers = (objInputFile.ReadAll)
arrTargets = Split(arrServers, vbTab)
objInputFile.Close



'WScript.Echo arrTargets(0)

For Each strTarget In arrTargets

Set oExec = WSH.Exec("ping.exe -n 2 " & strTarget)
RegEx.Pattern = "^Reply from ([^:]+).*$"


Do Until oExec.Status = 0
WScript.Sleep 100
Loop

Do Until oExec.StdOut.AtEndOfStream
Line = oExec.StdOut.ReadLine
If RegEx.Test(Line) Then IP = RegEx.Replace(Line, "$1")
Loop

WScript.Echo IP
objOutputFile.WriteLine IP

news:a2a96951-aa65-4acb-9650-f6115232580f@xxxxxxThe script works for me except:

1. I cannot write to the root of C: drive on my Vista computer. I assume the
same is true of W2k8 and Win7. I believe this can be corrected by using "Run
as administrator".
2. My firewall requires that I acknowledge all ping requests, so that
blocked the script.
3. I could not get the script to read a tab delimited file correctly.

When I run the script on a W2k3 client with no firewall in my test domain it
worked, after I wrote one computer name per line in the file hostnames.txt
and changed:

arrTargets = Split(arrServers, vbTab)

to:

arrTargets = Split(arrServers, vbCrLf)

However, the IP address for the last computer was listed twice until I added
a check for blank lines to the script. That is, I used:

For Each strTarget In arrTargets
If (Trim(strTarget) <> "") Then
.....

End If
Next

If you get an error, what is it?
