Hello, I have followed all steps to change credentials type to User Name and Password (new service tier, certificate thumprint, modifying ClientUserSettings.config file...) but when I start NAV and after asking for name/password it gets stuck for 2 or 3 minutes until this error pops up :

Application: Microsoft.Dynamics.Nav.Client.exe
Framework Version: v4.0.30319
Description: The application requested process termination through System.Environment.FailFast(string message).
Message: The connection to the server has been lost. The application will close.
Stack:
at System.Environment.FailFast(System.String, System.Exception)
at Microsoft.Dynamics.Nav.Client.WinClient.NavClientErrorHandler.ExecuteAndCatchExceptions(System.Func`1<Int32>)
at Microsoft.Dynamics.Nav.Client.WinClient.ExceptionHandler.DoExecute(System.Func`1<Int32>)
at Microsoft.Dynamics.Nav.Client.WinClient.StartWinFormsClient.RunCore()
at Microsoft.Dynamics.Nav.Client.WinClient.StartWinFormsClient.Run(Boolean)
at Microsoft.Dynamics.Nav.Client.Program.Main(System.String[])

I have dig into event viewer and found (besides this error) this warning:

Server instance: SECURE (its the name a gave the new NST with user/password credentials)
Tenant:
<ii>The service could not add service principal names because the service account could not be found in Active Directory.
Account: NT AUTHORITY\NET SERVICE
Service principal names:
DynamicsNAV/ALL-IN-ONE:20 (ALL-IN-ONE is my computer's name)
DynamicsNAV/ALL-IN-ONE:20</ii>

Any ideas how to solve it?

Thank you

Hi,

if you are using the NT AUTHORITY\NETWORK SERVICE as the Login Account, could you check whether the same is been granted permissions to the correct db which is mapped in the nav service instance mentioned in your issue?

Hi Mahesh, that Network service for Login Account is the same used for "standard" Windows Auth. NST, and it works fine with that service.

I also grant permissions for that Login Account at Local Computer Logical Certificate store.

Its kind of frustrating since it seems to begin opening, but menus wont show up, just the opening blue square of Microsoft Dynamics NAV.

seems your service is running. you can do following basic testing and configurations .

First open the database from development environment check if its opening correctly without error.

Second go to SQL server Management studio, then security, select the user which your service is running and check following permission,

under user mapping , select your db and bellow check following permissions,

public, db_owner, db_datareader, db_datawriter,

Now try to login into your rtc, if the error still same please let me know,

Regards
