Hi All, I am trying to use the Calvert's Unleashed DCOM client/server example (the one with the square() method in it) on a NTWS and an NT server. It seems to be working great when I have both the client/server on one machine however, when I put the server on a machine across the network, my client (with the help of that machine's IP address) can launch the server form a client that is sitting on my NTWS machine but can not use any of the functions exposed by the server. It seems like when the application is distributed across the network I can not get the correct interface handle ?? Am I suppose to change the access control on the server side?? What am I doing here wrong... can anybody help. Thanks in advance. Tanveer khan

Your having permission problems. Run DCOMCNFG on your server and make changes to who can lauch and run your DCOM object on that server.

Thanks for the reply Tom. I have tried the DCOMCONFG and set all the permissions(launch/access/..) to everyone. It still does not do anything. I can launch a server from a client machine but can not use any of the functions. Any other ideas?? Thanks indeed.

What's the error you get? Does your DCOM server use any resource from your local machine?

Actually I do not get an error. As a matter of fact I can not call a function! This is what happens: I start the client on dev-machine. launch the server on remote machine fom my client app. call a function and nothing happens. Do you have any idea what could be wrong?

Hi, Try using the MidasConnection instead of the RemoteServer object on your clientapp, and use it with borland3/bin/scktsrv.exe on the server machine. The only problem I have is getting the data on the client side to be correctly refreshed whenever the database is altered... i wanted this activision to be triggered on the server side.
