Get all the machines in the domain's OS key

hello
i think that this http://software.techrepublic.com.com/download.aspx?docid=286191 does what you want.
Note: I've never tried. :/

Sharath, here is VBScript that will give you the Windows XP product key from a remote PC.  If you have a list of computers in a file, we can make it go through those, and write, say:
COMPNAME:    xxxx-xxxx-xxxx-xxxx

to a file.

strPC = InputBox("Enter the computer to read the Windows XP from:", "Source Computer", objNetwork.ComputerName)

This link only shows the local computer serail no.How can i find all machines in the network's Licence key?

Rob

this is working great for 1 machine.can it take the names from a file and give results to a file....

Sharath, here you go:

Set objOutputFile = objFSO.CreateTextFile(strOutputFile, True)
While Not objInputFile.AtEndOfStream
      strComputer = objInputFile.ReadLine
      boolResult = Ping(strComputer)
      If boolResult = True Then
            objOutputFile.WriteLine strComputer & ": " & sGetXPCDKey(strComputer)
      Else
            objOutputFile.WriteLine strComputer & " could not be pinged"
      End If

Rob it works but if a machine is not found it throws and error.
Can you please give error on resume and to specify the error in the results file

By the way, are you still getting those GetObject failed messages?  I still have a feeling that some of your machines are either locked down to heavily, or there is something wrong with DCOM in them......

Regards,

Rob.

Thanks a lot Rob...

No worries.....you've got some interesting questions, but too many for me to look at them all.... :-)

Rob.

If possible take time on the Q's it would be very helpful to me....
