I have a 2000pro machine connected to a small network with an NT server and a couple of 98 machines. They are connected to the internet through a router then a dsl modem. The 2000pro machine will access the web without any problem on startup, then after a while (sometimes 30 min. other times hours) the internet access is lost. The other machines do not loose their connection. It doesn't matter what browser or email software is being used - tried a number with same results. The only way to get the connection back seems to be to reboot. There must be a solution. Please, advise?????
