asp website have the ability to create com+ objects via Server.CreateObject(). The com+ objects must be installed and registered on the server. You probably need to install and register the required dlls.
This will probably require reverse engineering the old server. You can get com+ tools, to lookup the dll names in the register. they are probably old, so hopefully you can find an installer. if not track down the dll, and copy and register on the new server.
you will need to send a little time learning com+
thankfully its been over a decade, since I've had to deal with com+
