My work has a domain controller running server NT. The person before me on a windows XP Pro computer that had limited or no connectivity issues and had manually configed the IP, DNS etc addresses. I'm trying to put this computer back on auto aquire IP address. When I do, I have limited or no connectivity. Running ipconfig /all I have a garbage IP address. I can ipconfig /release, but when I ipconfig /renew I get a timeout cannot contact DC. I also have the same problem on 2 DL360's running win 2k pro, but only on their 2nd NIC. When I try to join the domain I get Domain Name is Invalid or does not exist. Any ideas? Thanks, Joe

Thisi s a work computer ? no admin guy ? First look ata the cat5 cable going into the computer. When the pc is powered up, there should be a link light on the network card, right where you plug into the card. So if you remove the cable the link light goes out,back in and the light comes back on. If not that could be whats wrong.

Sounds like the DHCP server may be set for IP address reservations. If so, even if you set the machine to Obtain an IP address automatically, it would not be able to connect. This is because the server that is running the DHCP service has an IP address reserved for the MAC address of the NIC card. I would contact the System / Network Administrator to inquire if DHCP reservations have been configured for that machine.

You can get the MAC address of the NIC card by running the following at the command prompt:

ipconfig /all

The MAC address will be listed as the "Physical Address". If reservations have been set, the DHCP server should be handing out a specific IP address to that machine.

Have you tried to ping that machine from another computer that is on the network?
Have you tried to ping the loopback address? (ping 127.0.0.1 OR ping loopback)

If you are unable to ping the suspect machine once it has Limited or No Connectivity, or ping out from the suspect machine, there may be an issue with the NIC card.

Refer to the troubleshooting steps regarding the DHCP Client service and the DNS Client service. You may need to manually kickstart the services and reset them to start automatically.
