One of the most common error messages that I have encountered, but not always known by end users how to fix is ... "The server is unavailable. Check the configuration and network connection and try again". It can also be one of the easiest to fix!
Translation? Often the reason is that your "Microsoft Dynamics AX Object Server Service"...is not running.
To start that service...do this:
- Click Start > Administrative Tools > Server Manager.
Expand Configuration, and then click Services.
In the details pane, select Microsoft Dynamics AX Object Server 6.0$ InstanceName, and then click Start, Stop, or Restart, as applicable.
