I have a server with a mapped drive on it (maps to a directory on another server across the network).
I also have an application that writes a file to the mapped drive (regularly scheduled, but monitored by e-mail).
Periodically a router in between the first server and the second server gets rebooted (either due to maintenance or as part of a weekly reboot schedule - it gets rebooted whether it needs it or not).
If I have an Explorer window open and connected to the mapped drive during this reboot, the mapped drive becomes inaccessible. If I don't everything carries on tickety-bo.
Why? And is there something I can do about it?
