The LAN Speedtest Tool does not require installation - it is a portable tool. All you need is a network share or a drive letter to which you have write access and you are ready to go.

1. Use a network folder to which you have read and write permissions or create a new one. This can be a UNC path (example: \\Fileserver1\Data\Speedtest) or a path with a drive letter (example: U:\Speedtest).
2. Enter this path in the Speedtest tool under "Speedtest destination". Click on "Start". A window appears that checks the remote directory. The first two checks should show a green tick and the third a red X. Now click on "Create files now".
3. Click on "Repeat check". All three checks should now show a green tick. Close the window and perform a speed test.

Speedtest is a part of PingTool, which is also free.
