We have a shipping computer that, for some unknown reason, disconnects from the internet daily. It seems to happen around 3pm. The computer was set up before I was employed here, and it does not have any antivirus software or a firewall. I have assigned the computer a static IP address, but that did not solve the problem.

When I go to the command prompt, I can ping google.com and local computers, but I cannot browse the internet. I checked the scheduled tasks in the control panel and by typing 'at' at the command prompt, thinking maybe something scheduled the computer to disconnect, but I didn't see anything there. Out shipping software vendor insists nothing in their software would do this.

My boss says when the shipping software vendor was remoting into our computer and setting something up (before I was here), he thinks he remembers the tech saying he saw a setting that was doing this, but they never did anything about it, and now I can't find it.

If anyone has any input as to what could possibly be going on, I would greatly appreciate it. Thanks in advance.
