Thanks, but this parameter seems not working for me. I tried to set TcpNumConnections 0, 20, 100 without any changes. Still maximum 64 connections. After setting this parameter I always restarted my computer.
Now I tried my test on my colleague's computer (WXP SP2, the same as the my one, FB 1.5.2) and it works. I am able to create for example 2000 connections.
I don't see any difference between these computers.
