telnet some_ip 1433
On Windows 7 this line doesn't work. It says it cannot establish connection. I'm 100% percent sure that the server has this port open. For a friend of mine this line works.
I suspect 2 reasons:
- My ISP blocks this port.
- My system blocks it.
I turned off the firewall and windows firewall. Is there anything else I can do to make sure the problem is not related to my system configuration?
BTW, I don't know if it's important, but
telnet some_ip 80
I replaced the ip I tried to telnet with
