I have a problem with MFC CSocket.
Trying to Connect a Client works with “localhost” and fails with all other systems.
The same address and port is reachable with telnet in any case.
I have checked all firewall settings, I turned off firewall, nothing helps.
Trying to connect with a MFC CSocket, fails with time-out. After that the first try to connect with telnet also fails. The second and the subsequent calls are working normally.
The System is: Win7 Enterprise 64bit with Service Pack 1
Does anyone have an idea?
