Hi

Quick tip that may help...

NAV 2009 R2 - 3-tier setup getting the following error when accessing the NAV Web Services:

System.InvalidOperationException: General Error http://abc-svr-nav1:7047/DynamicsNAV/WS/Services ---> System.Net.WebException: There was an error downloading 'http://abc-svr-nav1:7047/DynamicsNAV/WS/Services'. ---> System.Net.WebException: The request failed with HTTP status 401: Unauthorized.


In the CustomSettings.config try
<add key="WebServicesUseNTLMAuthentication" value="true"></add>

and restart the service.
