How can I logon AX2012 on AX server itself ?

Hi,

I cannot logon AX2012 on AX server itself, but I can logon it from other client pc.

The error massage is "The Application Object Server name or port number is incorrect. Check the values in the Microsoft Dynamics AX Server Configuration Utility, and try again."

Rightly, it is correct the AOS name and port number of Server Config. and Client Config on AX server itself.

And, In windows ivent viewer log, "RpcBindingFromStringBinding returned 0x6a7". is it incorrect of network configuration of Windows Server ?

Thanks!
