Dropping network connection on computer

A colegue of mine is running a script which takes few hours on a computer in the lab and from time to time his test fails because is unable to find a file that is on the network drive. He sais that the network is dropping connection from time to time and that's the reason it fails. Whenever I run tests the computer is connected to all the netwrok drives and ping works just fine. Is there a tool that I can use to run a longer time to see if the computer loses connection to the network?
The PC has Windows XP Pro x64.
Thanks!

that was command not commang
c:> ping -N 1000 10.x.x.x
at the end it will give a result statement to show if any packets are lost

yes, I did, with 10000. It ran about 3 hours and never dropped. But those electronic engineers are so stubborn, they still say it's the network.
