I am using remote desktop to login Navision. The user account is a local account of the server PC as power users. But I got one strange error that telling me “The operating system cannot gain access to the file C:\Program Files\Microsoft Business Solutions-Navision\Client\ENU\fin.smt. Please check that the file type and attributes are correct.” But I have already checked that the user has already assigned the full permission to the Navision client folder. Why there is still a permission problem? Any solution except grant the user administrator rights? I tried, this problem only occured for Nav 4.0, but not in Nav 4.0 SP1 and Nav Sp2. Is it a bug of Nav 4.0?
