1.2. Slow copy & paste over network


When using copy and paste over a network in Windows Vista it takes a long time to complete and is sometimes unresponsive.


Auto-Tuning feature in early version of Windows Vista causes this problem when copying files over a network with non-Vista computers.


Option 1 - Install latest service pack for Windows Vista.

Option 2 - Disable Auto-Tuning feature in Windows Vista.

1. Open up an elevated command prompt.

2. Enter the following command to disable auto-tuning.

netsh interface tcp set global autotuninglevel=disabled

To re-enable auto-tuning enter the following command from the elevated command prompt.

netsh interface tcp set global autotuninglevel=normal

To view the status of the TCP global parameters:

netsh interface tcp show global
