Im trying to get computer serial numbers from about 200 NT 4.0 workstations but cant seem to get my script to run against the NT boxes...it works fine running it against the XP stations we have....does anyone have a script that would do this? squib

what do you mean by serial number?

Hi Steve, I mean the computer serial number from the manufacturer....you can get it with WMI (IdentifyingNumber)...on an XP machine but it doesnt work on an NT box...same computer/manufacturer.. On Error Resume Next Const wbemFlagReturnImmediately = &h10 Const wbemFlagForwardOnly = &h20 arrComputers = Array("Computer_Name_Here") For Each strComputer In arrComputers WScript.Echo WScript.Echo "==========================================" WScript.Echo "Computer: " & strComputer WScript.Echo "==========================================" Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_ComputerSystemProduct", "WQL", _ wbemFlagReturnImmediately + wbemFlagForwardOnly) For Each objItem In colItems WScript.Echo "Caption: " & WScript.Echo "IdentifyingNumber: " & objItem.IdentifyingNumber

there are quite a few third party programs that can do this for you like asset tracker.
