Does this ever happen to you? When try to copy a file and suddenly you want to cancel it or in my case I was try to write it over a network drive and I lost the connection.

But regardless what's the reason this annoying box just doesn't go away. Anyone know why this is happening? or How I can prevent such happen over and over again?

The same thing happens to me, but it's not always network related. – alex Sep 2 '09 at 6:47

Not sure why it happens but I get it too. To get rid of this annoying dialog you need to kill explorer and restart it:
* from task manager, processes tab, find explorer.exe and choose "end process"
* still in task manager select File - New Task - type explorer - OK

I dont think there is any way to genuinely fix this problem. Happens to me at random as well. It even happens on my laptop when i cancel a copying from a DVD drive.

Does the "More Details" arrow show any other info, like an error code, which you could search on?

Also, as paulsoares said, try a different copier. Certainly FastCopy, while being, erm, fast, also gives some info of problems. Try it once and see if it tells you anything useful.

Try a copy program that handles exceptions better like TeraCopy or Unstoppable Copier. Both free, fast, and far more reliable than Windows' native copy.

They will probably hit a network timeout in this case, too. There's not too much you can do about it. – Joey Sep 2 '09 at 5:11
thanks, I tried TeraCopy before, but I want to know why and what caused this. Are you suggesting the reason it stuck there is because the Windows Explorer itself doesn't have a good exception handles ? – Jonathan Sep 2 '09 at 5:14
Explorer isn't very forgiving when a network connection drops during a copy procedure or even when a document is open over the network. More often than not it just locks up, rather than timing out gracefully and moving on.... I'm not sure there's any "right" answer other than trying to locate the networking problem. – user8095 Sep 3 '09 at 1:51
