Microsoft Dynamics AX Help is a client and server based system that distributes and displays documentation.
1. The Help client is the Help viewer application that requests and displays documentation and gets installed with the Microsoft Dynamics AX client application.
2. The Help server responds to the Help viewer request for documentation. In addition, the Help server stores the files that contain the Help documentation.
Important: This Server-client Help system does not supply Help documentation for Enterprise Portal. You will have to install Enterprise Search to support help documentation for EP.

ü Typically, you can initiate a help request from either the client or developer workspace by pressing F1 /button / via command.
ü The client identifies the Help topic to retrieve. To identify the documentation for the form from where Help is initiated, the documentation has an ID property that has the same value as the ID of the form.
ü The client retrieves the URL of the Help web service. The first time that you request help, the client contacts the AOS to retrieve the URL of the help web service. The client then caches the URL and uses the cached URL for additional help requests.
ü The client calls the Help viewer. If the Help viewer is not running, the viewer is started. The call to the Help viewer includes the URL of the help server and the ID of the form.
ü URL can be updated/modified under path AX2012 > System Administration > Setup > System > Help system parameters.

One possible error which you might observe when you have SharePoint / Enterprise portal already installed in the machine is shown below:
Error: Web site (Help Server) is shown because the Default web site is not started. And this could be because SharePoint installation has taken over the Port 80 and kicked off the Default web site.
Solution: Go to IISManager (inetmgr) and then Edit bindings for the Default site to change the port number from 80 to something else (say 81).
After doing so, you can start the Website. This should resolve the issue shown above.
