Hi!

Thanks for answer. See comments below...

>Is this a DLL or an EXE? If a DLL, you shouldn't use CREATEOBJECTEX, but you should Export the MTS package from the server and do a client install on the local PC. If this is an EXE, you shouldn't be running it under MTS. In that case, recompile it as a DLL.

It is DLL. As I said, I tried to run it from another computer in the local area network, and it workes. Our network based completely on the TCP/IP protocol. I used exactly the same way of object instantiation. Why it does not work through Internet? What the difference?

I will try your suggestion about registering object from MTS package. However, as I remember from you lecture about MTS, such registering is required when you want to instantiate object using object name (for example, "comtest.comtest"). I used GUID of object as reference, that supposed to work without registering of MTS package. Is this a bug or working in the local area network by such way is just a weird thing?

>As for the modem problem, a bit more information will help. Are you connecting to your office network via the modem? Have you unregistered the COM component on the local machine and then done the client install as described above?

I connecting to my office using ISP via modem from W2000 (Dial Up + local area networ to define gateway).
No, I did no either client install or object registering on the client machine. Just ran exe with mentioned command.
