Let me start by describing our network setup. We have our modem connected to a firewall that is connected to a switch that feeds our office network. That switch has a five-port switch connected that is for our POS network. Our POS server is a customized desktop computer running Windows XP Professional and our POS software.
The problem is that the POS server is randomly dropping its internet connection. When this happens the internal POS network connections stay active. We can be logged into the server over the network and accessing files with no problem and the server will drop its internet connection so it is not a problem of something going into standby mode. We will then powercycle the five-port switch and the internet connection comes back up.
We have replaced the five port switch, the ethernet cable to both of the switches and changed the port in the large switch that feeds the five port switch with no success in eliminating the problem. We have run multiple different virus and malware scans on the server and they have all come up clean. I believe that the problem is software related but I am at a loss at to what could be the cause.
Thanks in advance for any suggestions you may have to offer.
