App unable to connect to share after a period of time

I've got a .NET app monitoring a network share and periodically it loses the connection.

The app itself does not send any login info, it runs under the current (Windows) user.

When this happens I can't connect to t开发者_开发问答he network share in Explorer either, I need to reboot the machine.

Is there any way programmatically in .NET I could get around this very annoying issue (ANGRY CUSTOMERS!)?

Thank you! Chris
