I use Samba to share the folders in Linux to Windows. There was a Microsoft Access database stored in one of the share folders. I have written a VB.Net application to connect to that Access database for retrieve data. It ran smoothly for somedays. However, problem occured several days ago. The connection to all the share folders being disconnected when the application was run. It was not always have this problem. Sometimes it was run without any problem. Does anyone know what is the problem and please help me to solve. Thank you.
