    Hi, I am empoyed by a small PD, and we can't afford a dedicated IT staff. I have taken on the role of an IT guy, but have no real expertise in the field. We have a server, a Netgear FS750T, and about a dozen wired computers. Every computer loses the internet sporadically. This issue has been present for almost a year, and I have not been able to figure it out despite hours and hours of research. One network person I spoke to over the phone told me to buy a new network switch and see if it corrects it, as it would be cheaper to do that than to hire him. (scary) The FS750T is at least 10 years old or so, and has never been properly maintained.

    We have a static DSL connection, and our ISP sent out a tech to look into the issue. I was not present when the tech came, but have been told that the technician reported the problem was not on their end, rather, it was on our end.

    The internet drop offs are getting to be more and more frequent. It used to be around every 20 minutes or so, now it seems about every 5. All computers on the network are affected by the internet drop off.

    The server is running Microsoft Windows Server 2003 Standard Edition, service pack 2. All of the PC's are running Microsoft Windows XP Pro (some Sp2, some sp3).

    So, "Server" is acting as the Dhcp server and DNS server for your network, right? But, internet access is through another machine or router with IP 10.0.0.50? Is that a router or computer? If a PC, please show its ipconfig /all.

    What is 192.168.0.1 and what is its role in your network?
