Does the DLL have any dependencies that may be missing on the 2000 system?

Have you set your DLL to work under COM+?

you need to add the components to a COM+ package for them to be accessed by your ASP page(s)

Do you receive a particular error message? It would greatly help to know a little bit more about the error.

Also you should check for security issues. It might be just that...

I just got my first DLL to function under Win2000 and (haha) Windows XP, however it fails under WinNT.

The main concern in win2000/XP was secuirty rights to execute, write, read. The IWIN_ComputerName account is used if the web site is set to Anonymous user login.
To solve the problem, I assigned the Everyone account, and gave full rights to any files the application requested.

Also, you need to assign the correct secruity to the MSVBVM60.DLL, otherwise you may get "Permission denied when creating object" error.

----

Now, anything I need to know to get a VB DLL to work on WinNT, I'm getting a "ActiveX object can't be created..."

In Win2000, registering it fix the problem when it came up. But in WinNT, it doesn't seem to.

I did register the dll

regsvr32 cms.dll

here is the code in asp

<%
dim myobj
set myobj = server.CreateObject ("cms.language")  
result = myobj.add ("test")

%>


The dll is name CMS
the class is name Language

here is the error message from IE

Error Type:
Microsoft VBScript runtime (0x800A01AD)
ActiveX component can't create object
/cms/cms.asp, line 10

line 10 is the line where I create my object

I put the cms in its own directory, tried in scriplibrary as well.

I resolve the problem partly by putting the dll on a fat32 drive instead of NTFS.  It seem that it is a security issues.....

If you put it in a different directory, other than the system directory (c:\winnt\system32) you will need to add the directory information in the registeration of the DLL.

for example:

regsvr32 c:\ItsOwn\Directory\cms.dll
