Error in COM+ while migrating from 2000 Server to 2000 Advace Server

[Adhik]

Hi,
I have one 3 tier architecture application running on Windows 2000 Server.

I have created replica of same machine on another machine where OS is
Windows 2000 Advance Server.

But when I port same running application on new machine i.e. Machine with OS
as Windows 2000 Advance Server, my middle tier (Active-X Dll, COM+
application) fails.

It throws common error
Invalid Procedure Call or argument

What could be the problem? Do I need to change any settings for running
application on Windows 2000 advance Server.

Thanks in advance, waiting for reply
Regards
Adhik

Where does it fail? on all function calls? Perhaps the function has some
machine specific/network specific code -- such as calling to Internet, etc.
Also, you might be missing some libraries this component depends on.
