Hi, I am trying to call a service on a remote server machine from a client machine connect through TCP/IP. I have created a DLL and registered the DLL at the server side. Launched DCOMCNFG and done the necessary settings at the server side. My question is at the client machine(s) side how will I specify where (which machine) to look for this service? I don't want to copy the DLL to the client machine even for any initial setup or registering. What I know: In a demo project's documentation I downloaded from microsoft website, they use the same server service exe (that was an exe not a dll) to register the service in client. Once we have done that we can use DCOMCNFG to specify which computer we want to look for this service. But here we need to copy the server exe to the client machine(s), I don't want to do that for the solution I am looking for. Environment: Windows XP, C++, ATL I greatly appreciate any help. Thank you for your time. -Kannan
