connection is blocked between 2 machines deployed with windows server 2012 RRS feed

  • Question

  • hi all,


    I have set up a server using Windows Server 2012 (namely Server-2012), with default settings on its firewall.


    since firewall blocks inbound connections by default, i create a new inbound rule to allow inbound connections, with folowing details:

       1) Programs and Services - fill in the javap program "c:\Java\jdk1.6.0_43\bin\java.exe".
       2) action - select "Allow the connection if it is secure". inside "customize", select the option "Allow the connection if it is authenticated and integrity-protected" , and the "override block rules" is checked.
       3) Remote Computers - add 2 clients "Client-2012" and "Client-2008R2" inside Authorized Computers.

    Client-2012 is deployed with Windows Server 2012, while Client-2008R2 is deployed with Windows Server 2008R2.


    The problem is, the connection is blocked between Server-2012 and Client-2012. However, connections can be established successfully between Server-2012 from Client-2008R2. so it looks Server-2012 is good, and Client-2012 is bad.


    To dig the issue deeper, I set up a new windows 2008R2 as sever - namely Server-2008R2, deployed with the same java program, and same Firewall inbound rule as Server-2012. And this time, both Client-2012 and Client-2008R2 can be connected to Server-2008R2. So Client-2012 looks good also, and it totally confuse me.


    The 4 machines are in the same network, join in same domain. And the connection between Server-2012 and Client-2012 just can't be established. I am new in Firewall and IPSec etc.


    Please kindly help and advice.


    Many Thanks,
