Hi,
I can't telnet any port locally on the server even if the port is open and I can't do telnet from this server to any other server.
I used port scan tools I ran it locally on the server it shows me that all the ports are blocked, but when I run this tool from another server to scan the open port on that server it shows me a group of opened port and I can telnet them.
NOTE: there are no Windows firewall enabled or any other security solution that blocking ports installed on the server.
