You can take a look at my NETRESOURCE class in the Files section; there's code there that can iterate and find available network resources. You could also try to use WNetAddConnection3() to attemt to attach the IPC$ resource to the remore server; if that isn't present, you aren't going to be able to use COM to connect to it. THere's sample code for iterating the netowrk resources and implementing WNetAddConnection3() in the class; ypou'll also need CLSHEAP to use it.
