Crashing NIPALUSB.sys

Hello,

I am including the Hijackthis log from a Dell Inspiron 8500 running a Micropulse Lidar system . I am using TurboFTP to upload files every hour. If I leave the Ethernet cable unattached, all is well and the system runs reliably. If I have the system accessing the internet, the computer crashes generally within 24 hours. I locked down the computer by using TCP/IP filtering, allowing only port 21. That worked for about 10 days, now the crashing is occuring again. Any ideas?
