Active Directory Error: Cannot create ActiveX component

Hello
I have an ASP.NET (2005) web application running on XP. I've add a reference to Active DS Type Library (activeds.dll) to my project. The code below works fine on my development machine but gives the error Cannot create ActiveX component error when I run it on a Windows 2000 server with service pack 4. I noticed that activeds.dll on my development machine is version 5.1.2600.2180 and the file activeds.dll on my server is 5.0.2195.6601.

I suppose I have 2 questions: 1) Does anyone know if this version difference is my problem? 2) If it is my problem, am I safe to copy the newer version from my development server to my production server?

Code:

---

                Dim IADsUser As ActiveDs.IADs = Nothing
                Dim intUserFlags As Integer = -1
                dim PasswordCantChange as Long = 64
                Try
                        IADsUser = CType(GetObject("WinNT://cincinnatistate/jane.doe,user"), ActiveDs.IADs)
                        intUserFlags = CInt(IADsUser.Get("userFlags"))

                        If (intUserFlags And PasswordCantChange) > 0 Then Return True

                Catch ex As Exception
                        log.LogError(Me.ToString(), "GetUserAccountControlValue", ex.Message, ex)
                        Return False
                Finally
                        IADsUser = Nothing 'Release unmanaged COM object
                End Try

Does your 2000 server have AD installed and running on it?

Hello Rob.
Thanks for your reply. I talked to our admin and they said that AD is not installed on the windows 2000 server.

Then you can not program against it for your server unless they install it. I am not 100% sure but I believe its a optional feature on 2000 while in 2003 and 2007 its required.

Hello Rob
Thanks for the reply. This doesn't make sense to me or my network admin. Since the code does run on my development machine, that would imply that I have Active Directory installed on my development machine and my admin says that I don't have it installed on that dev machine. I'm trying to connect to the AD "database" not the AD that is installed on that one specific server. He said we have AD installed on 4 of our servers, but certainly not all of them.

Well somehow you got the type library installed on your system (activeds.dll). Does the app run on the other server(s) that have AD installed?
Could it be a permissions issue on the server?

We are testing other servers now. The only problem is that the other servers may not have the .NET platform on them. The permissions issue might be a very possible problem.

You may have shown us the door to our problem. The code I'm using is not using a specific login account to access AD. How can I read these userFlags but not use the GetObject() method? I guess what i would like to do is make this same call, but use an ActiveDirectory method instead of the GetObject().
