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,
