“Connection with the Application Object Server could not be established”

Installing Dynamics AX 2009/2012 in two different domains or two different networks. AOS server in one domain ( network) and users and AX Client PC/ terminal servers in other domain ( network).
  1. When a AX client from a laptop attempts to connect to AOS you receive the following message or error “Connection with the Application Object Server could not be established”.
It is network problem and you can solve it.
Open host file (c:\windows\system32\drivers\etc\hosts) on the AX Client PC or Terminal Server. Add IP address of AOS server and AOS server name     AOSServer
in host file then Run the command nbtstat-R and start Dynamics AX Client.

  2. Hi Jagadis,
    This is because of the AOS service not started.start the AOS service and try it should work.
