When you use a network connection to copy a large file from one Windows Vista-based computer to another Windows Vista-based computer, you may receive an error message that resembles one of the following:

Error message 1

The connection has been lost.

Error message 2

There is a problem accessing shared folder path.
Make sure you are connected to the network and try again.

This problem may occur if the following conditions are true:

  • The network connection is slow or is prone to errors. For example, the network connection uses long-distance, slow-wired links or modems. Or, the network connection uses a wireless 802.11 or Bluetooth connection, and the network signal is weak. For example, the wireless network signal may be weak because of the distance from the access point or because of interference. The problem may also be affected by network traffic, by network retries, by packet losses, or by other factors that affect reliability of the connection.
  • The file that is being transferred is large. For example, the possibility of experiencing this problem is proportional to the size of the file that is being copied. For example, you may experience the problem when the file is approximately 100 megabytes (MB) or larger on an 802.11b 11 Mbps wireless network.


This problem occurs because, in some scenarios, Windows Vista may not retry the connection. Instead, the connection is dropped. When this problem occurs, the file transfer is not successful.
