Unable to connect to an Application Object Server

Posted on by Community Member

Hi,

I have problem opening my client ax. The following error occurs 'Connection with the Application object Server could not be found establish.' I install the client successfully. Only the AOS server can open AX.

Were using Dynamics AX 2012 R2, upgraded from ax 2012.

Any suggestion.

Thanks.

    According to them their is already trust relationship between domain. I can access a file from the AOS server in the workstation. I can also ping and telnet the server. The workstation computer domain is different but I login on this workstation using the same domain\userid and password that I used in the AOS server.

    So how can i prove to them that this is a trust issue? What kind of trust or credential ax needs to establish the connection?

    Also check the AOS port on which the AOS is installed and verify the same on your client configuration.

    Then you have your answer. :-)

    The AOS is unable to authorize your Windows user, and it sounds like your current user is either not on the same Active Directory Domain as the AOS, or the trust between the domains are not established.

    firewall is disabled on AOS server. I can ping and telnet the port from the client. Event error 110, Microsoft Dynamics AX. The client is installed on different domain from the AOS server.
