Authentication problem on single machine - others work

(0) ShareShare

Posted on by Absum 80

I have a problem for what I haven't found a solution anywhere. Hopefully someone here would be able to help me.

I haven't been able to log in to our NAV server for few weeks now. The problem exists only in my main work computer, which is bind to Active Directory and is running Win 8.1 64bit (if that matters). I am able to log in via web interface or by using any other computer that has RTC client installed. Nobody else has had the same problem.

I have removed my credentials from database and re-added myself to NAV without any change to subject, so the problem must be in my local computer.

Any ideas where to start with this?

    Figured this out. I have connected NAV servers C-drive with my domain admin credentials and for some reason, instead of credentials used to log in to desktop, RTC uses those credentials when connecting. Not always, just most of the time.

    A bit weird behaviour, but at least the problem got solved by adding both credentials to NAV server.

    Where do I change the login database? After starting RTC I get NAV splash screen and immediately after that I get  notification: "You are not authorized to sign in. Verify that you are using valid credentials, and that you have been set up as a user in Microsoft Dynamics NAV".

    hi,

    what's your error message ?

    first check,:  try lo login on "Cronus" Database with your user, can you login correctly on Cronus ?
