Its to do with the Application Language that the Client is using. 3081 is Australian English and Navision checks the Application language when you first log in. Check the Regional Settings in Control Panel. This doesnt always do the trick though. We had a case where one of our sites were being sent a dos application by one of their US suppliers that altered the regional settings whenever they ran it. Their only recourse was then to reboot that PC in order to reset the regional settings back.
