I located a vbs script some time ago were I get remotely obtain a machines serial number.

On Error Resume Next
Dim System
if Wscript.Arguments.Count >0 then
sSystem=Wscript.Arguments(0)
end if
ComputerName = InputBox("Enter the name of the computer you wish to query")
winmgmt1 = "winmgmts:{impersonationLevel=impersonate}!//"& ComputerName &""
Set SNSet = GetObject( winmgmt1 ).InstancesOf ("Win32_BIOS")
for each SN in SNSet
MsgBox "The serial number for the specified computer is: " & SN.SerialNumber
Next


pause



 Works fine on most pcs.  What I would like to do however is instead of checking 1 by one, I would like to check multiple pcs at once.  Does anyone know how I can do this?

Thanks

You could make it work down a text file.  This could be done just in VBS (sirbounty will no doubt help you with that here shortly as...) or you can use a batch file to call your VB script, e.g.

@echo off
REM Save as SerialNums.cmd
set source=complist.txt
set dest=serials.txt
echo ------------%DATE%  %TIME-------------->>%dest%
if not exist "%source%" then echo Unable to find computer list & goto end
for /f "tokens=1" %%a in (complist.txt) do cscript sernum.vbs %%a >> serials.txt
:end

REM sernum.vbs
On Error Resume Next
Dim ComputerName
if Wscript.Arguments.Count >0 then
   ComputerName=Wscript.Arguments(0)
else
   ComputerName = InputBox("Enter the name of the computer you wish to query")
end if
winmgmt1 = "winmgmts:{impersonationLevel=impersonate}!//"& ComputerName &""
Set SNSet = GetObject( winmgmt1 ).InstancesOf ("Win32_BIOS")
for each SN in SNSet
    wscript.echo ComputerName,SN.SerialNumber
Next

That works down a list in complist.txt, one per line of all your computers.

thanks

I must be doing something wrong

I created the complist.txt file and placed it in the same dir as the .cmd and vbs file

when I run serialnums.cmd, the cmd window appears with todays date and the word "dest"
the serials.txt file is generated but it only reads.....

OK, sorry made a typo in the entry for %time% as %time caused one of the issues here.  Try this:

@echo off
REM Save as SerialNums.cmd
set source=complist.txt
set dest=serials.txt
echo ------------%DATE%  %TIME%-------------->>%dest%
if not exist "%source%" then echo Unable to find computer list & goto end
for /f "tokens=1" %%a in (%source%) do cscript //nologo sernum.vbs %%a >> %DEST%
:end
start %dest%

REM sernum.vbs
On Error Resume Next
Dim ComputerName
if Wscript.Arguments.Count >0 then
   ComputerName=Wscript.Arguments(0)
else
   ComputerName = InputBox("Enter the name of the computer you wish to query")
end if
winmgmt1 = "winmgmts:{impersonationLevel=impersonate}!//"& ComputerName &""
Set SNSet = GetObject( winmgmt1 ).InstancesOf ("Win32_BIOS")
for each SN in SNSet
    wscript.echo ComputerName,SN.SerialNumber
Next

Can your computer resolve the names when you PING them for starters I suppose?  You might have to add them to the file fully qualified, i.e. name.domain.com?

all is well.  I went back and tried some more machine names and I was able  to get back a serial without the fqdm.

Thanks
