tcp/ip

If the address is a 169. address, it will not release, since there is no server.

Make sure that the tcp/ip properties for the NIC are set to obtain address from the server. Make sure that your connectivity is good, and that you are on the same network segment as the DHCP server. (The broadcase will not cross a router without help.) Save the configuration, then reboot. It should work.

If you have Netbeui protocol installed, you can test connectivity by clicking start, run, and typing \\server in the box and hitting OK, where "server" is the real netbios name of your server. (If you cannot find it this way, you may not be physically connected.)

Good luck.

Boot to safe mode and delete all protocols and network adapters. Run regedit and verify that HKEY_LOCAL_MACHINE --> System --> CurrentControlSet --> Services --> VxD is absolutely empty of the folders DHCP and HDCP Options (If the folders exist in the registry, then delete them).

Reboot in normal mode and install the adapters. If they are working in other computers, then they should work on this computer too. If the computer hardware is okay.

From what you are saying, the problem follows the laptop, not the NIC.

1. Have you tried taking the laptop to where you have a working computer, pulling the LAN connection off the working computer and plugging it into the laptop. Stupid as it sounds, it could be the wiring between your hub and the laptop, or could be a bad hub port.

2. If you plug a different laptop into the connection where the problem laptop was, does it work?

3. Go through the tcp/ip properties again, especially the bindings. It is possible, but not likely, that you have somehow disabled the binding between the card and tcp/ip. If your system has a bindings tab, try all the choices, and expand all the trees, checking for anything showing as disabled.

4. Do you have netbeui installed? If so, if you remove the tcp/ip protocol completely, can you connect with other computers? (This may again point to a physical wiring problem.)

Good luck.

GOOD ADVICE....HOWEVER, AFTER TRYING TO DELETE ALL PROTOCOLS, ALL BUT TCP/IP DELETED....ALSO VxD DOES NOT EXIST IN THE STRING IN THE REGISTRY...HAVING THE SAME PROBLEM ON 2 DIFFERENT MODELS, WITH DIFFERENT OS'S....THE NIC'S ARE FINE....COMPATIBLE WITH ALL OTHER LAPTOPS THAT I INSERT THEM TO, OVER THE NETWORK....ANNA777, ANY OTHER SUGGESTIONS....OS'S.....XP AND 2000

Stillatit...DONT MIND THE FRUSTRATION....YES I HAVE....DIFFERENT LOCATIONS....DIFFERENT NIC'S....CABLES....YOU NAME IT....ITS THE TCP/IP THAT WONT RELEASE THATS GOT ME....IS IT XP OR SOMETHING EMBEDDED WITHIN....LIKE I SAY, REMOVING THE THE NIC AND INSERTING IT....ZERO'S IT....EXCEPT FOR THE DHCP SERVER....ONCE IT ZEROS, DHCP COMES UP 255' ACROSS THE BOARD....RESET DHCP ON THE ROUTER THAT ACTS AS A SERVER, TO NO AVAIL....THANKS FOR AS MUCH AS YOU HAVE TRIED TO HELP....KEEP IT COMING IF YOU CAN....THAT MEANS YOU TOO,ANNA777

Under start->setting->network->Configuration->TCI/IP->Properties->IP is the Specify IP address checked or detect network settings not checked?

Is WINS configuration "use DHCP" not checked ?
