Wireshark-users: Re: [Wireshark-users] How to find the application sending a name request?
Something similar (but not network related) happens to
me.
I will use a file from my A: drive. I finish using
the floppy and remove it. In explorer, the A: is
still highlighted/selected/reverse video. When I
click on a C: drive file or folder, I get an A: drive
(Please insert a disk into drive A:) error sometimes.
Even though I don't want the floppy anymore, windows
tries to access it before going to where I clicked.
Perhaps windows previously accessed a network location
that has become unavailable.
