Check Microsoft Dynamics NAV Server and Web Services Availability
Microsoft Dynamics NAV 2009 and web services should be already installed.
Please, make sure that the web services are also installed. This can be checked in the Windows Services console (Start > Run > type services.msc):
If for some reasons Microsoft Dynamics NAV 2009 with web services is not installed yet, refer to the official Microsoft documentation.
After you have installed Microsoft Dynamics NAV Server, configuration settings are stored in the CustomSettings.config file. By default, this file is located in C:\Program Files\Microsoft Dynamics NAV\60\Service. If you have configured Microsoft Dynamics NAV Server during installation, then your settings are also included in this file.
Check that the value of WebServicesDefaultTimeZone is set to UTC.
