I am using Microsoft Windows Server 2003 R2 Enterprise Edition with the Service Pack 2. And my ISP is being blocked by the P2P, so I can make use of Image Shack's Torrent Drive service to my download of BT files. After the BT files are been finished downloading, then I tried to download it to my computer but failed in it. I use normal IE download, the download will starts correctly until 99% and at the time of going to finish, then the error message appear:-
An "Error Copying File or Folder" window with the message "Cannot copy file: Cannot to read from the source file or disk." I also don't know why this has occurred? Whose problems? I have also tried it several times but just receive the same error. Can somebody help?
Thanks in advance.

PS: This is the first time I making use of Win2003, before it I was making use of Win XP. As I noticed that Win2003 is more similar to Win XP, so then I decided to change it and install the Win XP in my computer. Is there any windows setting which I’ll be required to change?
