I have a Netgear wireless 4 port router/switch that connects to the internet thru my cable modem and it has been working faultlessly for months. I ahve the router setup to connect to my isp thru the modem and dynamically get assigned an IP and DNS servers. As i said this system has caused me no errors in the past.
The other day i built a windows 2000 server and whacked it on the network as a web server for testing etc and again no problems. the next day i installed active directory and DNS server on the server and the problems began. All of the computers on the network now work fine for about 15 mins at a time and then they all get DNS errors for about 5 mins (meaning they cant resolve any names even local ones) then they go back to being fine for about 15 mins then get DNS errors etc.
my PC's dont use the server as the DNS server - all the computers including the server point to the router for DNS. anyone have any idea what im doing wrong or whats going wrong? I dont want my server to be a DNS server or DHCP server - its purely a web server.
thanks in advance
