Cannot access Internet after DHCP switch

Locked

After converting one of out NT clients to DHCP, the user is unable to browse to the Internet.

Ipconfig indicates that all global/scope settings are correct (ie gateway/Wins/DNS etc).

Anyone have any earth shattering suggestions as to why this one client has this problem?

All other DHCP clients are fine, plus this one is OK when switched back to a static IP.

Not an earth shattering suggestion, but a recommendation:

Place the nic in another computer and see if the problem follows the network adapter. If the problem follows the nic, then the adapter is going bad.

Try another nic in the problem-computer. If the problem stays with the computer, then something (probably software wise) is not setup properly or conflicting with the settings.

It’s not the NIC – which works fine with a static IP.

After rebooting, if the problem still exists, make sure the IP that was statically mapped, is removed from the DHCP scope (you can reserve IP’s based on the NIC’s mac address).

Also, I would go to your WINS server (if you have one), and remove all instances of that server from the database. Lastly, I would run IPCONFIG /ALL on the computer, release all, and renew all.

Good luck

This is in response to your anwser to Anna, about the nic not being the problem, because it works with a static IP. Wrong assumption. Many problems can be attributed to outdated bios/firmware on NIC’s that get masked when you add static IP addresses to the network card. The problem comes from the card not starting properly at start up, because it is waiting for information from the network, but with static settings, it has all the information it needs when the computer starts and does not have to get that information later. My bet is with Anna that it is the network card.
