Hai

I've got a Dell laptop from the office which i wan't to use ad home.

Add the office it connects with a dhcp-server.

Add home i've got a dhcp-server as well, but i can't get it to work.

it just can't connect to dhcp.

A static ip doesn't function as well.

Cable's etc are tested.

Any sugestions?

Can't obtain/renew IP addresses from the DHCP server

Symptoms: 1) you have a DHCP client which may not be able to obtain/renew IP addresses from the DHCP server intermittently. 2) after setup a workstation to obtain an IP address from DHCP, the machine can't ping others and ipconfig /all shows Autoconfiguration IP Address. . . : 169.254.x.x.

Resolutions: 1) If this is XP, obtain the latest service pack for Windows XP.

2) Use the Network Diagnostics tool to identify any failed settings. To do this, go to Help and Support>Use Tools to view your computer information and diagnose problems>Network Diagnostics>Scan your system. When the process finishes, check for any items marked "FAILED" in red, expand those categories, and view the additional details about what the testing showed.

3) Assign a static ip on the client and ping the DHCP server. If you can't ping the DHCP server, check the connection and hardware.

4) If you can ping the DHCP after assigning static ip, check the DHCP settings.

5) Make sure no firewall is running on your LAN.

6) Run Repair this connection if it is XP. Or use netsh to reset TCP/IP configuration.

7) If it is win98/w2k, remove and reinstall TCP/IP.

8) Try to upgrade the new NIC driver.

9) Make sure you don't run out of IPs in the DHCP scope.

10) If you use a router as DHCP, you may want to upgrade the firmware.

Did delete and re-install tcpip, delete nic, etc etc.

No result.

i'm still logging in at the office with the same machine, no problem at all.

Strange huh

When you get home and hook up to your home network, open a command prompt window and try the following:

1) ipconfig /release

2) ipconfig /renew

3) exit

This should drop any of the current IP info. tied to your adapter that may be left over from the office or from an autoconfiguration.

Barring that, check to make sure the DHCP server is working. Try connecting to it from another machine if you have one.

Good luck.

Thanks for your reply

I did try the ipconfig command before without result, but after a driver upgrade the ipconfig command does work.

So thanks for helping me sort it out!!
