Hi everyone, I've been reading about this opening ports problem on everything I could find on google, but I have still not found a definite answer for my problem.
Here's my situation... I'm trying to create a "message" like server using Visual C#... First, I created a test client and test server program which basically just sends a string to the server then receives a string back and ends.
It seems to work when I open the server, and the client connects to localhost:17777 which is a random port I picked. But, when I use the IP address for the client to connect to, it gives an exception that it couldn't connect.
Now, i'm using Win XP Pro. I DID have the XP firewall running, then turned it off. Either one did not help. I added the port to ports that should be open. But it still didn't help.
Running netstat -an states that port 17777 is LISTENING.
Now, my guess is that something internal in WinXP is causing all these ports to be CLOSEd. But I have no idea how to open just this ONE simple port. Can anyone shed some light? I heard something about IIS but I don't know what that is..could that be it?
Thank you.
