  • Cant get two Servers to Talk to each other

    I have two computers that will not talk to each other through ports, however they talk to and from other computers on the network. I've tested 6 other computers it works.

    I have pinged the devices and that works..I have used telnet to test ports to and from other computers. So far the only issue I have is the communication between each other. One is a 2008r2 server the other is server 2012 Standard. One is an exchange server Server 2008 R2 Enterprise the other is a dell Appassure appliance Server 2012.

    Nothing in the computer logs about. I also tried changing the IP's.

    I was first brought into the Picture because appassure will not backup one server the Exchange box. Upon further examination no ports connect to each other. For example I can not telnet to and from each other on any port. No windows firewalls or third party Firewalls. No antivirus on either machine.

    I dont know what category to put this in so i'd thought I'd start here.

    Please any insight to this would be helpful.

    First you need to tell us what you mean by the statement "I have two computers that will not talk to each other through ports". Give us specific details about the problem.

      I can not connect to or from either computer through their respective ports to each other. If I have port 80 and 443 open I can telnet to those ports through dns or IP. The appassure port is 8006. The port numbers don't seem to be an issue as I cant connect to any ports the computers have open unless I use different computers. The only problem is communication between them both.

        Can you post the results from each server for both of these commands:
        Code:
        ipconfig /all 
        Code:
        netstat /ano | find /I "listening"
