    Hi,

    Does the Desktop Client work properly?
    Did you install SQL and ServiceTier properly (combined on one Server or splitted?)
    Are SQL and NAV Service running?

    Also, please dont overuse exclamation marks. Nobody wants to be shouted at.

    Please check with NTLM Authentication to True in CustomerSetting.Config file and restart the Middle tier although I am not suggesting this solution.

    If it works then you should check SPNs for SQL and Navision. It might be the case that your credential is not passed from Navision middel tier server to SQL Server.

    SPNs are created automatically at time of Navision installation. So, you should first check for SQL SPN and then Navision server.

    <!--
    Turns on or off NTLM authentication protocol for SOAPServices and ODataServices
    false: Use SPNEGO for SOAPServices or Windows for ODataServices (recommended)
    true: Use NTLM only
    -->
    <add key="ServicesUseNTLMAuthentication" value="true" />

    Use "ServicesUseNTLMAuthentication"" = false as per it is recommended by Microsoft.

    Please let me know if it helps you.

    hi,

    in the attached files the error encountered and SOAP Services ODATA Services Config,

    NTLM Authentication in the beginning is not checked by default in the general Fast Tab, I was checked and the error still persists.
