I am developing a distributed application. Both client and server are Win2000 machines. My server performs callbacks to the client, so for that to work I have been using same username/password on both machines. By for new application I cannot use same credentials and my callbacks dont work. I am trying to use COM+ on a server side. I have compiled my server into mt dll and registered in on the server box. Then I created a com+ application with that dll as a component. I am testing all of this with:
o=CREATEOBJECTEX('{D407290F-D119-4D34-A260-29CC71372834}', '192.168.1.157')
where GUID is a CLSID.
I am getting this error:
classfactory cannot supply requested class

And another detail: The server application needs to have an interface. In previous model I used EXE and everything worked fine but even if COM+ works for me I am not sure if a DLL can have an user interface.

Can someone share some ideas?

Thanks
