Michael,

It sounds like the physical relocation was not successful. Did you check the
new connection to see if the cable is intact? Can you try another cable?

Is the DHCP server issuing addresses otherwise? Are there any errors indicated
by the server?

Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.

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.
