NAV 2016 NAS + Regional Settings

Hi,

I have a problem concerning the regional settings of a NAS running a job queue.

If I log in with the user on the server which has the MiddleTier service running of the NAS, I get the correct regional settings (Dutch (Belgium)).
The service account has a user personalisation in NAV with has the Dutch (Belgium) language, the Dutch (Belgium system locale. But every time the job queue executes an entry, my regional settings of Dutch (Belgium) are neglected.
The report should print the date in format DD/MM/YY and now it's printed in the format MM/DD/YY.

Can someone help me?

Kind Regards
Tom
