Some time ago we get several problems with Help Server. Simply when we wanted to access help from Microsoft Dynamics Ax 2012 client we get following problems:

1. Error:

Unable to contact server http://ServerName:Port/DynamicsAXHelpServer/HelpService.svc

To troubleshoot this problem you need to check on client if you are able to access the help server service from Internet Explorer. The url for Help Server service you can find in System administrator > Setup > System > Help system parameters. When in IE you get error like:

Could not load type ‘System.ServiceModel.Activation.HttpModule’

then you need to apply following KB article:

2. The other problem we can see is that we get page with “No results” and we cannot see the content of help. For this issue there can be several causes:

a. Double check in Internet Explorer if you can retrieve help files by accessing ie. http://ServerName:Port/DynamicsAX6HelpServer/Content/Microsoft/EN-US/UserHelp/6a9bdc61-b19e-4cea-8890-805a4ccba8b2.htm?DocumentSet=UserDocumentation&ContentLanguage=en-us&ResourceLanguage=en-us

b. Double check if Windows Search Service is up and running

c. Check if content directory is indexed and indexing is finished (Control Panel > Indexing options)


d. In indexing options for File Type htm and html are “Index Properties and File Contents (You need to click Advanced button)

c. If you go to Advanced properties of directory Content the property “Archive and Index attributes” is set up to “Allow files is this folder to have contents indexed in addition to file properties”


d. This is very strange but if help server content is installed in directory of SharePoint ie: C:\inetpub\wwwroot\wss\VirtualDirectories\8082\DynamicsAX6HelpServer\Content the Search Service does not return correct files and the Help Server does not work correctly. So far we have no idea why does it happen but the workaround is to uninstall Help Server and install it on Web Application which physical path points to ie:  C:\inetpub\wwwroot\8082\DynamicsAX6HelpServer\Content
