virtualbox.org

I have a Windows XP guest running in VirtualBox installed on Windows 7. I have a folder on my host shared as a volume in my guest (using VirtualBox shared folder). The guest is running BitTorrent and is writing its downloads to that volume. Without exception, it gives me an error that the destination cannot be reached after about 1 minute. When I restart the download, it works just fine, only to lose connection again after another minute.

Does anyone have any thoughts on this subject? Thanks.
