I am running SBS 2003 and I have a few XP clients. I try to keep things simple as I am not all that knowledgeable. My problem is that the internet access has become erratic meaning that you need to click on the website you want to go to a number of times before it actually loads the page. My setup is a two NIC setup and if I plug the cable modem directly into one of the clients the internet service is fine. I have checked cables and they are fine. What could be causing this problem? Do I need to replace the network card or can I test the network cards some how to see if the problem is occuring from there. I have run antivirus and spyware and all was clean. I would appreciate any assistance.
