network card problem

[mobiker]

I'm having a problem with a NIC The computer is conected to a router connected to a cable modem. It had been working fine then all of the sudden it won't connect any more. I have checked all connections and have uninstalled NIC and reinstalled have even tried a new NIC. What shows up if I check under: control panel-network connections-local area connections-status-support:

Internet Protocol (tcp/ip)
Address type: Automatic Private Address
IP address: 169.254.15.114
Subnet mask: 255.255.0.0
Default Gateway: blank


I have other computers connected that work fine the show:


Internet Protacol (tcp/ip)
Address Type: assigned by DHCP
IP address: 192.168.0.*
Subnet mask: 255.255.255.0
Default Gateway: 192.168.0.1

If I click repair on the problem computer it has a pop up that reads

The following steps of the repair operation failed:
renewing IP address

Please contact your network admin. or ISP.

I tried moving to a new router and network that didn't help still same problem. Could the problem be the motherboard. I have aldo repaired the install of the operating system (WIN XPpro). And updated the bios on the motherboard.

It sure looks like a bad patch cable. Try another and check the LEDs at both ends for connectivity.

Also be sure that the router setup is allowing enough IP addresses (scope). Most default to 5 IPs. Add a sixth and one inevitably drops off.

I have tried a different cable and can hook a differnt cpmputer up to same cable and it works fine its just this computer that doesnt work.

Is it possible that there are two PCs on the network with the same name?

[mobiker]

no I checked for that I built all the computers myself and name them differntly. This is one I built for a friend and it worked fine for over a year then it just quit working. I then brought it to my house to see if different router and cables would help and even put a different NIC in and it all comes out to the same result.

I have a extra hard drive I thought I would try putting it in and doing a fresh install to see if perhaps the operating system is corrupted.

I already tried doing a repair install and it didn't help could the motherboard be bad and cause this problem

[BipolarBill]

I doubt it.

For what its worth I did a fresh load of Win XP on a spare hard drive and everything works great. It must be something was corrupt in the windows program. Bill thanks for the help.

That seems to fix most problems. I hate to recommend it, but there it is.
