Convert SID to HEX

I have a SID that I want to convert to Hex.
I found the following script on the web but it isnt' working.

Set oConvert = CreateObject("ADs.ArrayConvert")
objSid="S-1-5-21-603733758-2039161187-5522801-19473"
strHexSid = oConvert.CvOctetStr2vHexStr(objSid)

WScript.Echo strhexsid

When I execute the above script I receive error box.
Script:    C:\sidtohex.vbs
Line:       3
Char:      1
Error:     ActiveX component can't vreate object: 'ADs.ArrayConvert'
Code:     800A01AD
Source:  Microsoft VBScript runtime error

If anyone could let me know what I'm doing wrong or if any dlls need to be registered or what ever I need to do I'd appreciate is.

Or if you could tell me how to pull a users SID in an NT4 domain in a Hex format that will work as well.

From the looks of things, you need to install this from MS:

I placed the files in the system32 directory and I registered ADs.dll
I now get the following error.

Script:    C:\sidtohex.vbs
Line:       5
Char:      1
Error:     Type mismatch
Code:     800A000D
Source:  ADs

Actually if I can pull the SID from an NT4 domain in Binary, Decimal or Hex.
Or convert a SID S-1-5-21-603733758-2039161187-5522801-19473 to Binary, Decimal or Hex
That would solve the problem.

Sakuya su,
I found that site but was unable to make heads or tails of it.
If you post the script you used I can place my own SID in it and run it.
Thanks

have you included that ADs.dll to your project in references(library reference)?
If not try to include it through menu Project->References.

I should have listed in the beginning that I not a programmer.
I'm not sure what you mean by Project->References.
The above lines of code are all that exist in the .vbs
There is no larger program that this is a piece of.
I registered the ADs.dll from the system32 directory.
All I need is for this to convert the SID to either Binary, Decimal or Hex.
Or pull the SID from an NT4 domain in Binary, Decimal or Hex.
Thanks

in Hex

If you want please let me know your email and I'll give you the Converter I made, which converts string to Hex, it can be modded to do the otherway round too and maybe to add Endian Format, its from the code I showed oyu in the ealier post

Do you want a string value that contains the Hex representation of a SID, or an actual number variable in your VB program?  SIDs are quite large in memory, and VB doesn't handle numbers larger than 32 bit signed.

If you just want a string, that's pretty straightforward.  Since Sakuya's going to email you a solution, I won't spend time on writing one right now.  I only have a function to convert in the other direction handy (from Hex to SDDL).  For giggles, I'll post that one:

Function HexStrToSDDL(strSid)
  ' Function to convert hex Sid to decimal (SDDL) Sid.
  Dim arrbytSid, lngTemp, i, j, nSubDWords
  Dim nLowIndex, nHighIndex
 
  ReDim arrbytSid(Len(strSid) / 2 - 1)
  For j = 0 To UBound(arrbytSid)
    arrbytSid(j) = CInt("&H" & Mid(strSid, 2 * j + 1, 2))
  Next
 
  ' Read revision, authority identifier, and number of subauthority identifier DWORDs
 
  nSubDWords = arrbytSid(1)
 
  lngTemp = arrbytSid(2)
  lngTemp = lngTemp * 256 + arrbytSid(3)
  lngTemp = lngTemp * 256 + arrbytSid(4)
  lngTemp = lngTemp * 256 + arrbytSid(5)
  lngTemp = lngTemp * 256 + arrbytSid(6)
  lngTemp = lngTemp * 256 + arrbytSid(7)
 
  HexStrToSDDL = "S-" & CStr(arrbytSid(0)) & "-" & CStr(lngTemp)
 
  ' Read subauthority values (little-endian DWORDs)
 
  For i = 0 To (nSubDWords - 1)
    nLowIndex = (4 * i) + 8
    nHighIndex = nLowIndex + 3
    If (nHighIndex > UBound(arrbytSid)) Then nHighIndex = UBound(arrbytSid)
   
    lngTemp = 0
    For j = nHighIndex To nLowIndex Step -1
      lngTemp = lngTemp * 256 + arrbytSid(j)
    Next
   
    HexStrToSDDL = HexStrToSDDL & "-" & CStr(lngTemp)
  Next
End Function
