Actually, it'd be using CREATEOBJECTEX(), the principal difference from the calling standpoint is the need to specify a target server by NetBIOS name (or IP address in the case of NT/Win2K at least. You can use the local system by referencing it's name in the second parameter.)

Well, a .DLL in and of itself must be an in-process server; to run it on a remote server, you need something like MTS to serve as a host. Direct instantiation of an in-process .DLL runs the .DLL on the same machine and in the same memory space as the caller.
