NAV RTC client crashes on ntdll.dll

isanta

Hi.

We have a production server, where we host all our customers.
It works as a terminal server.
The server has NAV2013R2, 2015, 2016 and 2017 installed on it.

Recently, we started experiencing a problem with starting NAV clients (RTC).
It happens only when a developer or consultant open up Navision client on this server.
This doesn't have an effect on terminal sessions for our customers.

From the error message it says (sorry, the server is set to Danish language):

From where I can understand that something bad happened to ntdll.dll file. But the variety of problem that this one brings is huge.
So, I didn't find an answer for this specific case as of yet.
Sometimes APPCRASH issue doesn't bother us, but then it reappears again.
I spotted interesting thing in the event log, as the error description points to the printer (I marked it bold in the text below)

Here is what I've found in the Event Logs:

Did somebody experience that before?

It only happens when u run an object from the development environment? If so, open the NAV DevEnv in administration mode, it will no longer crash when openning the Client, that's a version error.
