NAV 2013 SOAP Services Connectivity Issue

MattKeyes

I have installed NAV 2013 at a client in a three tier configuration, and the RTC and Web Client work like a charm. I am trying to install Jet Reports (which uses the SOAP services in 2013), so I am now testing the SOAP services to make sure they work.

Jet Reports shows an Unauthorized 401 error when I test a connection.

When I connect to the SOAP service in a browser on the app server (i.e. http://servername:7047/DynamicsNAV70/WS ... e/services), it works fine.

When I use that same address on another machine, I get a HTTP 400 Bad Request error page (even from the machine Jet is installed on which is showing the 401 Unauthorized).

If I use the address shown in the Event Viewer (http://servername.domainname.com:7047/D ... S/Services) from any machine, I get the HTTP 400 Bad Request error.

There is nothing logged in the SQL Logs or the Event Viewer, and, like I mentioned above, everything else is working beautifully.

Does anyone have any troubleshooting advice here?

Check 'Use NTLM Authentication' to disable Kerberos.

Use NTLM Authentication
Specifies whether NTLM authentication is enabled for SOAP and OData web services. Enable this setting if you are using PHP or Java to initiate a web services connection to Microsoft Dynamics NAV.
