I'm working in Windows Server 2008.
I have a very basic C# forms application (not a service) that is listening on a port, say 56112. When using telnet I can connect from the localhost and send and receive data. For some reason I cannot remotely connect to the application. I know I have a connection because I can telnet to 23 on the remotely fine.
I've opened this port on the firewall, created rules in/out in advanced firewall, disabled the firewall completely, and more.
Any suggestions would be great!
This is the telnet output:
Microsoft Telnet> open server.cc 56112
Connecting server.cc...Could not open connection to the host, on port
56112: Connect failed
The nmap output indicates that the port isn't even open?! I've created the rules for in on Windows Firewall (+ advanced firewall) and still cannot see those changes remotely.
