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.
