i have trouble to enable the concurrent feature in my design.
i talked with the company's IT guy but he failed.
we tried to enable the port 9000 for the iCDBNetLauncher and ports 10000-10100 for iCDBNetServer
but it didnt help.
i can a sure that when the firewall is disabled the concurrent feature works fine.
so it must be a firewall configuration problem.
i've helped with the concurrent administrator's guide it also didnt help.
so for final solution the IT guy and me tried to enable all ports in the firewall.
still, doesnt work.
i dont know what more can i do. this feature is most important.
