Sometimes you will receive an error when you try to open the AX client.
And that error is " The Server is unavailable. Check your configuration and network connection and try again. "
Why it happened ?
That probably because your AOS Service is not running when you try to open the AX client.
So, follow the step by step below to resolve this error :
1. Open the Control Panel (控制台).
2. Find the Administrative Tool (系統管理工具) in the Control Panel.
3. Find the Services (服務) in the Administrative Tool.
4. Find your AOS Service ( It is usually named "Microsoft Dynamics AX Object Server ......") and start it !
5. After the AOS Service status is already become "Running", you can try to open the AX client again, and the error will not show out!
