We are using AX 2009. we have a distributed environment with different servers for AOS, SQL Portal Reporting etc.
We have 7 affiliate offices who are also using the Dynamics Application from our server.
We have done two way forest trust between domains so that the users at the affiliates can use the Application from our office.
Additionally, each affilliate office and also our company has different sites where domain controllers have been installed.
recently, I had to demote one domain controller at a site office of our company, After this the users from affiliate offices cannot use the Dynamics ERP application. They get the error
“Connection with Application Object server could not be established”
Please advice .
