I had to made some hardware changes. All the computers are running windows XP. I changed out to a Motorola 2210 modem, d-link dir-825 router and DGS-1008G switch.
Everything was fine until I made this change. I now have internet. My big problem is that I can not access all my computers on my network for sharing. I have tried everything. If I go into the network places to add a network place, I see the network and then I click on it. Then it just sits there. Any help would be appreciated. If I need to give more info, please ask.
