How to fix corrupted IP Configuration

To fix a corrupted IP Configuration,
1) for Win9x, NT, ME and W2K, you may want to remove and re-install TCP/IP.
2) If it is win9x, you may try to run c:\windows\ws2bakup\ws2bakup.bat to restore the original settings.
3) If you get "DHCP server unreachable" while using ipconfig /renew, you may want to update the network card drive or go to NIC configuration to change the media type matching the speed.
4) For XP, you can't uninstall TCP/IP (Uninstall is grayed out). You will use the Windows XP command line utility netsh.exe to reset all IP-related Registry settings to their default values. To do that, enter the command: netsh int ip reset filename, for example, netsh int ip reset ipreset.t.xt

IP address conflicts

SYMPTOMS: when trying to set the IP address on a NIC, you may receive the following error message: "The IP address `XXX.XXX.XXX.XXX` you have entered for this network adapter is already assigned to another adapter `Name of adapter`. `Name of adapter` is hidden from the network and Dial-up Connections folder because it is not physically in the computer or is a legacy adapter that is not working. If the same address is assigned to both adapters and they become active, only one of them will use this address. This may result in incorrect system configuration. Do you want to enter a different IP address for this adapter in the list of IP addresses in the advanced dialog box? "

RESOLUTION:
1. If you click Yes, you see the TCP/IP properties where you can change the IP address. Then assign the different IP.
2. If you click No, the IP address is assigned to the network adapter. To resolve this problem, uninstall the ghosted network adapter from the registry: At command prompt, type `set devmgr_show_nonpresent_devices=1`, and then press ENTER. Type `Start DEVMGMT.MSC`, and then press ENTER. Click View, and then click Show Hidden Devices. Expand the Network Adapters tree and right-click the dimmed network adapter, and then click Uninstall.

XP client unable to obtain IP addresses from the DHCP server

RESOLUTION: To resolve this problem, obtain the latest service pack for Windows XP.

Why the ipconfig shows 0.0.0.0 ip even you have assigned a static ip

Question: I have assigned a static ip, subnet to the computer, but the ipconfig shows IP address is 0.0.0.0 and subnet mask 0.0.0.0.. Why?

Answer: An existing IP address on the network has the same IP address. You may use tracert ip, WINS and DNS records to find out another computer using the same IP.

If your laptop users frequently disconnect from one network segment and reconnect to another network segment, they may not be able to access the second network. Resolution will be run ipconfig /registerdns.
