I have a PC in my store and it cannot connect to the network. The PC's in the store are hooked up to a switch, and the switch is on a router. All other PC's have no problem getting the IP address from the Router.
Heres the trouble shooting I did;
First, I checked the NIC, it is working fine. I pinged it, 127.0.0.1 and it sent replies back successfully.
Second, I replaced the network cable, same issue. So I unplugged the cable and plugged it into my laptop, I was able to connect to the network.
Third, I did ipconfig, and it said the cable was disconnected. After doing it a few times, it came up with a 0.0.0.0 IP address. So I tried to do ipconfig /renew, and it said it could not find the DHCP server. Sometimes it will assign itself a 169....... IP address(which I know is a local IP address only).
Fourth, I did a chkdsk /p from the recovery counsel. It found a few errors, but nothing changed.
I know the PC works up to the NIC, and I know that the router works on sending IP addresses to the PC's, and I know the cable works to the PC. So it seems that it has to be a software issue(my guess).
Is it an issue with TCP/ip? I heard that the TCP/IP stack can get corrupted. If so, how do I run a fix for the TCP/ip, or it there other things I can do to fix this?
