Ok, I'm going through about 40 computers with all sorts of crap on them. What I do is put in my HDD with XP loaded, I test the computers, make sure everything works and then format the drive that is currently in it. I'm having a weird problem with the embeded NICs not working for some reason though. I can take the HDD out of a comp that is on the network, move it into another comp with the same motherboard and the NIC won't work. On Friday I had 3 computers I put notes on the embeded NICs did not work. Today I decided to try them again since it was a little suspicious that ALL 3 would have their embeded NICs fail. Well... they worked just fine today. I couldn't get the NICs working all Friday, shut down the comps and left them, turned them on Monday and they work fine. What is up with that? So I was excited that it was then working... I switch the HDD to the 4th computer and the NIC doesn't work again. I have the correct drivers. In one case Windows automatic updates downloaded themselves but yet I had a 192.168.x.x address and could not ping and could not ipconfig /renew. How is that even possible? It is like the NICs are failing to hear back from DHCP. And sometimes I will see like LAN connection 9 has limited or no connectivity. There is only 1 LAN connection on each computer. I'm going a little crazy here.
