To convert a string formatted GUID to its hexadecimal string form, follow these steps:

1. Paste the following code into a .vbs file.

   '================================================================
   ' Replace the value of strGUID with an actual GUID
   '================================================================
   strGUID = "{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}"  
   Set obj = GetObject("LDAP://<GUID=" & ConvertStringGUIDToHexStringGUID(strGUID) & ">")
   MsgBox "The octet guid for " & obj.Get("displayname") & " is " & obj.GUID
   
   '================================================================
   ' ConvertGUIDtoOCTET function
   '================================================================
   Function ConvertStringGUIDToHexStringGUID(strGUID)
    Dim octetStr, tmpGUID
   
   For i = 0 To Len(strGUID)
    t = Mid(strGUID, i + 1, 1)
    Select Case t
    Case "{"
    Case "}"
    Case "-"
    Case Else
    tmpGUID = tmpGUID + t
    End Select
    Next
   
   octetStr = Mid(tmpGUID, 7, 2)' 0
    octetStr = octetStr + Mid(tmpGUID, 5, 2)' 1
    octetStr = octetStr + Mid(tmpGUID, 3, 2)' 2
    octetStr = octetStr + Mid(tmpGUID, 1, 2)' 3
    octetStr = octetStr + Mid(tmpGUID, 11, 2)' 4
    octetStr = octetStr + Mid(tmpGUID, 9, 2)' 5
    octetStr = octetStr + Mid(tmpGUID, 15, 2)' 6
    octetStr = octetStr + Mid(tmpGUID, 13, 2)' 7
    octetStr = octetStr + Mid(tmpGUID, 17, Len(tmpGUID))
   
   ConvertGUIDtoOCTET = octetStr
   End Function
   

2. Run the script.
